General Description of Business

     We develop, manufacture and market high technology materials and
derivative products for precision use in industrial, medical,
telecommunications, military and aerospace applications.  We use
advanced material growth technologies coupled with proprietary high
precision fabrication, micro-assembly, and thin-film coating production
processes.  The resulting optical and optoelectronic devices are
supplied to manufacturers and users of a wide variety of laser,
detection, military and telecommunication components and systems.  A
key strategy is to develop and manufacture complex materials from
elements of chemistry's periodic table.  We focus on providing critical
products to the heart of our customer's assembly lines for products
such as high power laser material processing systems, fiber-optic
telecommunication transmitters and receivers, military fire control and
missile guidance and advanced medical x-ray systems.  We believe we are
a market leader for high power (CO2) and YAG laser optical elements,
military infrared optical components, and x-ray and gamma-ray detectors
for the nuclear radiation industry.

     Our United States production operations are located in
Pennsylvania, Florida and California and our international production
operations are based in Singapore, China, Mexico and Belgium.  In
addition to sales offices at each of our manufacturing sites, as well
as, in Iowa, California and Massachusetts, we have sales and marketing
subsidiaries in Japan and the United Kingdom.  Approximately 37% of our
revenues are for product sales outside of the United States.

     Our products are key optical and optoelectronic components used in
the laser, military, nuclear radiation detection, and telecommunication
industries.

     - Our laser-related products include laser gain materials for
       solid-state lasers and many of the high precision optical
       elements used to focus and direct laser beams to target or work
       surfaces.  The majority of our laser products require advanced
       optical materials that are internally produced.  Our vertical
       integration from material growth, through fabrication and thin-
       film coating provides us with a significant competitive
       advantage.

     - Our military infrared products include, targeting and navigation
       systems that utilize advance optical materials.  The vertical
       integration of our manufacturing processes for these military
       applications provide us with a significant competitive
       advantage.

     - Nuclear radiation detector products are based on the
       semiconductor material Cadmium Zinc Telluride (CdZnTe).  These
       detectors are attractive to customers due to the increased
       performance, reduced size, improved ruggedness and lower voltage
       requirements as compared to traditional technologies.

     - New products have been recently introduced for the
       telecommunications industry.  These products, which are building
       blocks for next generation optical networks, demand the high
       precision and rigid metrology core competencies that have been
       developed for our laser product lines.

     We are at the forefront of advanced material growth research,
development and high volume production.  Over the past four years we
have expanded our material growth development to include single crystal
Silicon Carbide (SiC) for use in blue and green Light Emitting Diodes
(LEDs), diode lasers and high performance electronics.  Significant
progress has been made in this relatively short development period and
at the present time we are working closely with potential customers to
qualify and further develop our products.

Our Markets

     Our business is comprised of five markets:

     1)  Design, manufacture and marketing of optical and electro-
         optical components, devices and materials for infrared, near
         infrared and visible light lasers and instrumentation by our
         II-VI business units and VLOC subsidiary.

     2)  Manufacture and marketing of x-ray and gamma-ray solid-state
         radiation detectors and components for medical, industrial,
         environmental and scientific instruments by our eV PRODUCTS
         division.

     3)  Design, manufacture and marketing of infrared products for
         military applications and optical and electro-optical
         component devices for infrared lasers by our Laser Power
         Corporation subsidiary acquired in fiscal 2001.

     4)  Production of micro-fabricated and micro-assembled devices for
         telecommunications.

     5)  Development of single crystal growth and fabrication of
         Silicon Carbide (SiC) substrates for use in the manufacture of
         high temperature electronics and blue and green high
         brightness LEDs.

     Our reportable segments, in accordance with Statement of Financial
Accounting Standards No. 131, ''Disclosures About Segments of an
Enterprise and Related Information,'' currently are optical components
(which encompasses markets 1, 4 and 5 above), radiation detectors
(which is market 2 above) and the Company's Laser Power Corporation
subsidiary (which is market 3 above).

     Laser Components Market.  In recent years, increases in laser
component consumption have been driven by continued worldwide
proliferation of laser processing applications.  Manufacturers are
seeking solutions to increasingly complex demands for quality,
precision, speed, throughput, flexibility, automation and cost control.
High power CO2 and YAG lasers provide these benefits in a wide variety
of cutting, welding, drilling, ablation, balancing, cladding, heat
treating, and marking applications.  For example, automobile
manufacturers use lasers to facilitate rapid prototyping, production
simplification, efficient sequencing, and computer control on high
throughput production lines.  Manufacturers of recreation vehicles,
motorcycles, lawn mowers and garden tractors cut, trim and weld metal
parts with lasers to achieve flexibility, high consistency, reduced
post processing and lower costs.  Furniture manufacturers utilize
lasers to provide easily reconfigurable, low-distortion, low-cost
prototyping and production capabilities that facilitate the
manufacturing of customer specified designs.  On high-speed processing
lines, laser marking provides automated date coding for food packaging
and computer driven container identification for pharmaceuticals.

     We provide optical elements and components for both CO2 and YAG
laser systems.  In addition to use by original equipment manufacturers
(OEMs), a replacement part aftermarket exists in support of an
estimated current worldwide installed base of over 100,000 industrial
YAG and CO2 lasers.

     Solid-State Radiation Detection Market.  Solid-state radiation
detectors and components are sold primarily to companies engaged in the
manufacture of medical diagnostic, medical imaging or industrial
gauging equipment.  In an increasing number of applications, the use of
gamma- or x-ray radiation enables more rapid and accurate measurement
of medical conditions or industrial quality than can be observed by
other methods.  Solid-state detectors based on CdZnTe are making
inroads against older, more established technologies such as
cryogenically cooled germanium detectors or sodium iodide scintillators
coupled to photomultiplier tubes.  CdZnTe detectors have already been
substituted for the older technologies in applications where increased
accuracy, simpler operation, portability and lower cost are required.
CdZnTe is beginning to enable new medical and industrial applications
not feasible with the older technologies and is used routinely in
cancer probes, bone densitometry systems and process control
instruments.

     We believe the annual market for all solid-state radiation
detectors is currently over $250 million and growing at 10% per year.
Digital radiography (the recording of digital x-ray images) represents
the largest market segment followed in order by nuclear medicine (the
detection or imaging of radioactively tagged materials in the body),
industrial gauging, radiation monitoring and nuclear safeguards/non-
proliferation.    Presently, we believe that the CdZnTe addressable
market has grown to over $50 million of the over $250 million solid-
state radiation detector market.

     During the next several years, the performance of CdZnTe and other
solid-state detectors will be improved through additional research and
development, creating the potential for digital imaging to replace x-
ray film in a myriad of traditional radiography applications.

     We believe that the market for CdZnTe detectors and imagers will
grow faster than the overall market rate of 10% because of several
factors, including:

     - the strong migration toward ''film-less'' detection methods that
       enable the direct recording of digital images or videos which
       can be stored, recalled and transmitted via the Internet;

     - the desire for lower radiation dosage;

     - the desire for simpler and safer operation at room temperature;

     - the increasing requirement that equipment be ''intrinsically
       safe'' in environments where a spark might start a fire;

     - the general trend towards equipment miniaturization; and

     - the need to inspect, document and control quality at additional
       points within the manufacturing process in a wide range of
       industries; for example, the measurement and control of film
       thickness during the painting of automobile bodies.

     Equipment manufacturers increasingly desire to procure fully
tested, packaged components rather than devices that must be qualified
and assembled.  We believe that this trend will require leading
suppliers to provide products containing ever-higher levels of signal
processing and, as a result, the market will place high value on
suppliers having strong applications engineering capabilities and a
focus on customer relationships.

     Military Infrared Optics Market.  The military infrared optics
market is comprised of a demand for several critical products primarily
windows, window assemblies and domes.  Windows and window assemblies
are utilized in thermal imaging systems that provide night vision,
targeting, and navigation systems.  These systems are installed in
various platforms, including ground vehicles, helicopters and fixed-
wing aircraft.  Domes are utilized as a protective cover for infrared
guided missiles.  Missile sizes range from small, man-portable designs
to larger designs mounted on ground vehicles, helicopters and fixed-
wing aircraft.  These infrared optics products are sold primarily to
the U.S. government and its prime contractors for use in night vision,
thermal imaging and guidance systems.

     Currently, the demand for military optics is being driven by
upgrades to existing platforms such as the F-16 and F-18 fighter
aircraft and the introduction of high performance/lower cost mid-wave
infrared sensors.  This complements the current market of long-wave
infrared optical products that we have traditionally produced while
providing additional growth.  Demand for mid-wave infrared optical
components from materials such as sapphire, ALON and Spinel will
likewise increase to meet this demand.

     The U.S. government is directing several research and development
programs to field defensive anti-missile systems using laser
technology.  These programs include the Air Borne Laser (ABL) and Space
Borne Laser (SBL) programs.  These programs require high performance
coatings that must withstand extremely high laser energies and must be
reliably coated onto large aperture optics including windows, domes and
mirrors.  Funding for these programs is increasing and is likely to play
a much larger role in the defense budget in coming years.  Soon ground-
based laser energy projection systems will receive additional funding to
further the development of the Starfire Optical Range (SOR) and the
Nd:YAG lasers used in those systems.

     Telecommunications Components.  In recent years increases in
demand for multimedia information, entertainment, and voice and data
communications have resulted in a corresponding increase for greater
bandwidth.  This has resulted in an increase in fiber-optic network
deployment, which subsequently has created increased demand for
precision telecommunication optical components.

     Optical and opto-electronic materials are fabricated into
telecommunication elements such as:

     - Waveplates
     - Air Gap Etalons
     - Prisms
     - Mirror Blocks
     - Filter Taps
     - Polarization Rotators

     In telecommunication systems certain optical components help lock
the laser output wavelength to the proper channel on the
telecommunication system's grid.  Other optical components function as
an isolator, which is a device that ensures that laser light in a fiber
optic is not directed back into the source of transmission.  Another
component such as a prism functions as an optical multiplexer.

     Silicon Carbide Electronic Materials Market.  Silicon carbide is a
wide band gap semiconductor material that offers high-temperature,
high-power and high-frequency capabilities in applications that are
rapidly emerging at the high-performance end of the optoelectronic,
telecommunication, power distribution and transportation markets.
Silicon carbide has certain inherent physical and electronic advantages
over competing materials such as silicon and gallium arsenide,
including the ability to operate at up to 400 degrees Centigrade (750
degrees Fahrenheit) and the capability to conduct heat away from
operating devices up to twice as fast.  Typically, either silicon
carbide or gallium nitride layers are deposited on a silicon carbide or
alternative substrate and desired optoelectronic or electronic devices
are fabricated in the resulting material structure.  Silicon carbide
based structures are being developed and deployed for the manufacture
of a wide variety of microwave and power switching devices while
gallium nitride based structures are already standard in the
manufacture of blue and green light emitting diodes and blue laser
diodes.

     We believe that wide band gap semiconductor devices incorporating
silicon carbide materials technology will penetrate a wide range of
applications in the optoelectronic, telecommunication, power
distribution and transportation markets during the next decade.  For
instance, blue and green LEDs built on silicon carbide substrates offer
the promise of higher output power than devices currently built on less
expensive but thermally insulating sapphire substrates.  The
realization of this promise will establish silicon carbide substrates
as an important building block in high brightness computer driven signs
or displays, in high brightness automotive lighting and in the
replacement of incandescent and eventually fluorescent lighting by high
power, high efficiency solid-state lamps.  High power, high frequency
silicon carbide microwave devices promise to rival gallium arsenide
devices in telecommunication base station transmitters and silicon
devices in both commercial and military air traffic radar applications.
Silicon carbide high power, high-speed switching devices promise to
improve the performance and reliability of motor controls in a wide
variety of applications and could play a key role in the evolution of
the electric car.

Our Strategy

     Our strategy is to build businesses with world-class, high
technology materials capabilities at their core.  The following current
business activities follow this model:  CO2 and infrared optics based
on Zinc Selenide (ZnSe) and Zinc Sulfide (ZnS), near infrared and
visible laser components based on YAG and Yttrium Lithium Fluoride
(YLF), and solid-state radiation detectors based on CdZnTe.  Consistent
with this strategy, our initiative to enter the optoelectronic and
electronic substrates business is predicated on the establishment of
Silicon Carbide (SiC) capabilities.  In every case, we subsequently
manufacture precision parts and components from these materials using
established but evolving expertise in low damage surfacing and micro
fabrication, thin-film coating, and exacting metrology.  A substantial
portion of our business is based on long-term contracts with market
leaders, which enables substantial forward planning and production
efficiencies.  In addition, industry leading product quality and
delivery performance allows us to achieve comparatively high operating
margins in major segments of our business.  We intend to capitalize on
the execution of this proven model and continually gain market share
for laser optics and components, telecommunication devices, solid-state
radiation detectors, and optoelectronic/electronic materials and
substrates.

     - Continue Investment to Gain CO2 and YAG Market Share Worldwide.
       We continually invest in our manufacturing operations worldwide
       to increase production capacity.

     - Enhance Our Reputation as a Worldwide Quality and Customer
       Service Leader.   We are committed to understanding our
       customers' needs and exceeding their expectations.  We have
       established ourselves as a consistent high quality supplier of
       components into our customers' assembly lines.  In many cases we
       deliver on a just in time (JIT) basis.  We believe our on-time
       delivery record and product return rates are the best in the
       industries we serve. Our quality mission statement is, ''We
       pledge to exceed our internal and external customer requirements
       through employee dedication to continuous improvement.''

     - Pursue Strategic Acquisitions and Alliances.   Some of the
       markets we participate in remain fragmented and we expect
       consolidation to occur over the next several years.  We will
       pursue strategic acquisitions and alliances with companies whose
       products or technologies compliment our current products, expand
       our market coverage, increase our addressed market or create
       synergies with our current capabilities.  We intend to identify
       acquisition opportunities that accelerate our access to emerging
       high growth segments of the markets we serve.

     - Pursue Military Infrared Systems Programs.   We believe our
       Laser Power Corporation subsidiary is a leading supplier of
       optics for military infrared systems.  The Exotic Electro-Optics
       (EEO) subsidiary of Laser Power Corporation is committed to
       capturing new military contracts and currently has significant
       contracts in place with every major military prime contractor.
       The recent completion of our Large Optics Coating Facility
       (LOCF) will enable us to pursue the increased U.S. government
       defense funding for programs directed towards defensive anti-
       missile systems using laser technology.  This facility is unique
       in the industry placing itself as one of the few coating
       laboratories to provide high performance coatings that must
       withstand extremely high laser energies.  Laser Power has
       several proprietary coatings that are the enabling technology
       for these systems.

     - Continue Extension of Technology Leadership in the Gamma- and X-
       ray Detector Field.   We believe our eV PRODUCTS division is the
       leader in the manufacture of solid-state gamma- and x-ray
       detector devices and components.  Cadmium Zinc Telluride
       (CdZnTe) handheld probes in the medical field allow the
       introduction of new cancer location techniques.  CdZnTe based
       imaging arrays are being introduced in nuclear medicine.  CdZnTe
       is being developed for direct read digital radiography, which
       will allow a physician to view relevant parts of the body in
       real time using a fraction of the x-ray dose required with film.
       Our eV PRODUCTS division is working on these medical
       applications with market leaders worldwide.  The high pressure
       Bridgman growth process for producing CdZnTe is a materials
       expertise unique to the Company.

     - Utilize Proven Materials Growth Expertise to Perfect Silicon
       Carbide (SiC).   We are a proven provider of hard to grow
       materials and opto-electronic crystals.  We intend to leverage
       our skills and experiences in commercially producing ZnSe, ZnS,
       CdZnTe, YAG and YLF to move rapidly forward with our SiC
       development program.  We intend to gain market share and become
       the reliable second source of SiC substrates to the worldwide
       marketplace in the next three years.  We will utilize our low
       damage fabrication experience and exacting metrology in
       achieving this position.

     - Extend Proven Fabrication, Thin-Film Coating, Assembly and
       Exacting Metrology Capabilities to Telecommunications
       Components.   We are a respected supplier of waveplates,
       etalons, frequency doublers and other highly precise components
       to the YAG laser and related markets.  We have recently extended
       our high accuracy fabrication, thin-film coating, assembly and
       exacting metrology expertise to the manufacture of the passive
       components such as: micro-waveplates, miniature air-gap etalons
       and micro-prisms that are critical to the performance of the
       receivers, transmitters and add-drop modules being deployed in
       the rapid expansion of fiber optic networks.  We have
       established a stand-alone facility in Florida for the production
       of telecommunications products and will closely monitor market
       place demand positioning ourselves to enable us to respond
       quickly to changes in market place demand.

near-infrared applications which are used to control or alter visible
or near-infrared energy and its polarization.

     Solid-State Radiation Detectors.  We design, manufacture and
market CdZnTe room temperature, solid-state radiation detectors
combined with custom designed low noise front-end electronics.  New and
expanding applications in industry, medicine and research are fueling
increased demand for our products.  Our solid-state CdZnTe nuclear
radiation detectors are attractive because of their reduced size,
improved ruggedness, and lower voltage requirements as compared to
traditional detectors based on scintillator/photomultiplier or cooled
germanium technologies.

     CdZnTe-based imaging arrays can be used in both nuclear medicine
(internally emitted gamma-rays) and radiography (x-rays from an
external source).  In nuclear medicine, CdZnTe makes feasible a new
generation of gamma cameras, offering much improved position
sensitivity and the ability to produce images using lower doses of
injected radioactivity.  In radiography, higher density CdZnTe can
provide much improved sensitivity to the higher x-ray energies used in
some of the newer diagnostic techniques.  Direct-read digital
radiography cameras are being developed which, if successful, will
allow the physician to view the relevant part of the body in real time,
reducing the time required for diagnosis.

     Military Infrared Optics.  We produce optics for military infrared
systems including thermal imaging, night vision, targeting, and
navigation systems.  These optics comprise missile domes, electro-
optical windows and assemblies and imaging lenses and filters.  Our
precision optical products utilize optical materials consisting of zinc
selenide, zinc sulfide, germanium, silicon, sapphire, AMTIR, ALON, and
Spinel.  The vertical integration of our manufacturing gives us a
unique capability to design, fabricate, coat, and assemble these
complex systems in-house.  These products are currently utilized on the
M1 tank, Bradley fighting vehicle, Apache Helicopter, F-14, F-16, A-6
military aircraft, and others as well as future platforms including the
Comanche Helicopter and Joint Strike Fighter (JSF).

Research, Development and Engineering

     Our research and development policy calls for the pursuit of a
program of internally funded and contract research and development
totaling between 5 and 8 percent of product sales.  From time to time
the ratio of contract to internally funded activity varies
significantly due to the unevenness and uncertainty associated with
most government research programs.  We are committed to accepting only
funded research that ties closely to our growth plans.

     We devote significant resources to research, development and
engineering programs directed at the continuous improvement of existing
products and processes and to the timely development of new
technologies, materials and products.  We believe that our research,
development and engineering activities are essential to our ability to
establish and maintain a leadership position in each of the markets
that we serve.  As of June 30, 2001 we employed 142 people in research,
development and engineering functions.  Ninety-two of our employees are
engineers or scientists.  In addition, manufacturing personnel support
or participate in research and development on an ongoing basis.
Interaction between the development and manufacturing functions
enhances the direction of projects, reduces costs and accelerates
technology transfers.

     During the past year, we have made focused investments in:

     - Silicon Carbide Substrate Technology:   We presently have
       several crystal growth furnaces producing silicon carbide ingots
       at our Pennsylvania manufacturing facility.  In addition, ingot
       slicing and substrate polishing facilities are in place and
       qualification products are being sampled to key customers.

     - Large Diameter YAG Manufacturing:   Our research and development
       activities in this area are focused on producing materials that
       will accelerate the evolution of kilowatt-class YAG lasers.
       Achievements in process control and reliability are rapidly
       transferred into production at our New Port Richey, Florida
       manufacturing facility, largely due to effective teamwork and
       crossover between our development and manufacturing personnel.

     - Telecommunication Device Development:   We have developed
       microfabrication, thin-film coating and metrology techniques to
       enable the manufacture of several new devices of high interest
       to telecommunication customers.

     - High Performance CdZnTe Materials:   The marketplace success of
       eV PRODUCTS depends on our capability and capacity to produce
       radiation detectors with ever-higher sensitivity, resolution and
       efficiency at lower cost.  Key advancements have been achieved
       and will continue to be sought in the production of larger
       single crystal ingots as well as in the fabrication techniques
       for the manufacture of monolithic arrays of closely spaced
       detectors.  As improved performance is indicated, new
       applications and market potential are opened to CdZnTe products.

     The development of our products and processes is largely based on
proprietary technical know-how and expertise.  We rely on a combination
of contract provisions and trade secret laws to protect our proprietary
rights.  We intend, however, to protect our rights when they are, in
our view, infringed.

     Research, development and engineering expenditures were
$8,118,000, $4,040,000 and $3,358,000 for the fiscal years ended June
30, 2001, 2000 and 1999, respectively.  For these same periods, the
customer and government funded portions of these expenditures were
$5,083,000, $1,651,000 and $1,436,000.

Marketing and Sales

     We market our products through a direct sales force in North
America, Japan, Southeast Asia, Belgium and the UK, and through
representatives and distributors elsewhere in Europe, Asia, and South
America.  Our market strategy is focused on building market awareness
and acceptance of our products.  New products are constantly being
produced and sold to our established customers in the laser component
market places.

     Each of our product lines is responsible for their own worldwide
marketing and sales functions, as follows:

     1) The laser component businesses share many common customers and
        sell through our subsidiaries II-VI Japan and II-VI UK as well
        as through a common distributor in most of Europe.

     2) The Laser Power Corporation subsidiary marketing and sales
        responsibility is handled through a direct sales force in the
        United States and Belgium as well as through its distributors
        primarily in Japan and Europe.

     3) The eV PRODUCTS marketing and sales initiative is handled
        through a direct sales force in the US coupled with
        manufacturers' representatives.  An array of distributors and
        representatives are used throughout the rest of the world.

     4) The telecommunications business unit shares its marketing with
        our VLOC subsidiary.

     5) The management and technical staff work closely with potential
        customers providing samples and deliverable products from our
        wide band gap wafer materials activities in SiC.

     Our sales force develops close relationships with our OEM
customers worldwide.  All divisions actively market their products
through targeted mailings, telemarketing, select advertising and
attendance at trade shows.  Our sales force includes a highly trained
team of application engineers to assist customers in designing, testing
and qualifying our parts as key components of our customers' systems.
As of June 30, 2001, we employed 64 individuals in sales, marketing and
support.

Manufacturing Technology and Processes

     A majority of the products we produce depend on our ability to
manufacture difficult optical, opto-electronic or electronic materials.
The table below shows these key materials and the processes used to
produce them.

Product Line            Materials Produced   Growth Process Utilized
--------------------    ------------------   --------------------------

- Laser Components      ZnSe and ZnS         Chemical Vapor Deposition
- Laser Components      YAG and YLF          Czochralski
- SolidState Detectors  CdZnTe               High Pressure Bridgman and
                                               Conventional Bridgman
- SiC Substrates         SiC                  Physical Vapor Transport
                                               and Axial Gradient
                                               Transport

     The ability to produce these difficult materials and to control
the quality and yields is an expertise of II-VI.  Processing of these
materials into finished products is difficult to accomplish; yet the
quality and reproducibility of these products are critical to the
performance of our customer's instruments and systems.  In the markets
we serve there are a limited number of suppliers of many of the
components we manufacture.

     The network of our worldwide manufacturing sites allows products
to be produced in the most cost-effective area of the world.  We
believe our cost to produce our infrared and near infrared components
are the lowest among all competitors.  We employ numerous advanced
manufacturing technologies and systems in all product-manufacturing
facilities.  These include automated CNC optical fabrication, high
throughput thin-film coaters, micro precision metrology and custom-
engineered automated furnace controls for the crystal growth processes.
Producing products for use across the electromagnetic spectrum requires
the capabilities to repeatedly produce products with high yields to
tolerances in the nanometer range.  We embody a technology and quality
mindset that gives our customers the confidence to utilize our products
in a just in time basis straight into the heart of their production
lines.

Sources of Supply

     The major raw materials we use are Zinc, Selenium, Hydrogen
Selenide, Hydrogen Sulfide, Cadmium, Tellurium, Yttrium Oxide, Aluminum
Oxide and Iridium.  We produce virtually all of our Zinc Selenide
requirements internally, although small quantities of Zinc Selenide may
be purchased from outside vendors from time to time.  We also purchase
Zinc Sulfide, Gallium Arsenide, Copper, Silicon, Germanium, Quartz,
optical glass and small quantities of other materials for use as base
materials for laser optics.  We purchase Thorium Fluoride and other
materials for use in optical fabrication and coating processes.  There
are more than two external suppliers for all of the above materials
except for Zinc Selenide, Zinc Sulfide, Hydrogen Selenide and Thorium
Fluoride, for each of which there is only one proven source of merchant
supply.  For most materials, we have entered into annual purchase
arrangements whereby suppliers provide discounts for annual volume
purchases in excess of specified amounts.

     The continued high quality of these materials is critical to the
stability of our manufacturing yields.  We conduct testing of materials
at the onset of the production process to meet evolving customer
requirements.  Additional research may be needed to better define
future starting material specifications.  We have not experienced
significant production delays due to shortages of materials.  However,
we do occasionally experience problems associated with vendor supplied
materials not meeting contract specifications for quality or purity.  A
significant failure of our suppliers to deliver sufficient quantities
of necessary high-quality materials on a timely basis could have a
materially adverse effect on our results of operations.

Customers

     Our customer base for our laser component products consists of
over 5,000 customers worldwide.

     The three main groups of customers for our laser component
products are as follows:

     - Leading original equipment manufactures and system integrators
       of high power industrial, medical and military laser systems,

     - Laser end users who require replacement optics for their
       existing laser systems, and

     - Scientific and military customers, including the U.S. military
       and its allies, for use in advanced targeting, navigation and
       infrared imaging systems.

     For our solid-state radiation detector products, our customers are
manufacturers of equipment and devices for industrial process control,
nuclear medicine, x-ray imaging, environmental monitoring, nuclear
safeguards and nonproliferation, and health physics.  We are currently
dependent on a limited number of key customers for this product line.

     For our telecommunications component products, our customers are
telecommunication companies who utilize our products as discrete
optical elements for active and passive components for frequency
stabilization, DWDM (dense wavelength division multiplexing)
applications and optical networking.  We are currently dependent on a
limited number of key customers for this product line.

     Our silicon carbide electronic materials product sales to date
have been limited and we do not have an established customer base for
this product line.

Competition

     We believe that we are a leading producer of products and services
in our addressed markets.  In the area of commercial infrared laser
optics and materials, we believe we are an industry leader.  We are a
leading supplier of infrared optics used in complex military assemblies
for targeting, navigation and thermal imaging systems to every major
military prime contractor.  We are a leading supplier of CdZnTe
substrates and devices for x-ray and gamma-ray detectors and
components.  We are a significant supplier of YAG rods and YAG laser
optics to the worldwide markets of scientific, research, medical and
industrial laser manufacturers.

     We compete on the basis of product quality, delivery time, strong
technical support and pricing.  Management believes that we compete
favorably with respect to these factors and that our vertical
integration, manufacturing facilities and equipment, experienced
technical and manufacturing employees, and worldwide marketing and
distribution provide competitive advantages.

     We have a number of present and potential competitors, many of
which have greater financial, selling, marketing or technical
resources.  A competitor of our production of ZnSe is a division of
Rohm and Haas Co.  The competitors producing infrared and CO2 laser
optics include Coherent in the United States and Sumitomo in Japan, as
well as several companies producing limited quantities of infrared and
CO2 laser optics.  Competing producers of YAG materials and optics
include the Litton Airtron Division of Litton Industries and a division
of Saint-Gobain.  Competing producers of infrared optics for military
applications are in-house fabrication and thin film coating
capabilities of major military prime contractors, such as Raytheon
Corporation.  Competing producers of CdZnTe and CdZnTe detectors
include Acrorad in Japan and Imarad in Israel.

     In addition to competitors who manufacture products similar to
those we produce, there are other technologies or materials that may
compete with our products.  The market for the nuclear radiation
detector materials is in its infancy and could be affected by competing
technologies.

Bookings and Backlog

     We define our bookings during a fiscal period as incoming orders
believed to be deliverable to customers in the next twelve months net
of any order cancellations.  Certain long-term research and development
contracts exceeding twelve-month may be booked in their entirety, but
in no event would exceed twenty-four months.  For the year ended June
30, 2001, our bookings were $132.7 million compared to bookings of
$83.0 million for the year ended June 30, 2000.  We believe that the
increase in bookings reflects continued acceptance of our products over
competing technologies and vendors and shows that our customers desire
our high quality products delivered in a timely manner and the
acquisition of Laser Power Corporation.

     We define our backlog as customer orders available for shipment in
the next twelve months and certain long-term research and development
contracts not exceeding twenty-four months as of the end of the fiscal
period.  As of June 30, 2001, our backlog was $44.7 million compared to
$27.2 million at June 30, 2000.  The increase in backlog is primarily
reflective of higher bookings during fiscal year 2001 and the
acquisition of Laser Power Corporation.

Employees

     As of June 30, 2001, we employed 1,158 persons worldwide.  Of
these employees, 142 were engaged in research, development and
engineering, 800 in direct production and the balance in sales and
marketing, administration, finance and support services.  Our
production staff includes highly skilled optical craftsmen.  None of
our employees are covered by a collective bargaining agreement, and we
have never experienced any work stoppages.  We have a long-standing
policy of encouraging active employee participation in selected areas
of operations management.  We believe our relations with our employees
to be good.  We reward our employees with incentive compensation based
on achievement of performance goals.

Patents, Trade Secrets and Trademarks

     We rely on our trade secrets and proprietary know-how to develop
and maintain our competitive position.  We have not pursued process
patents due to the disclosures required in the patent process and the
relative difficulties in successfully litigating process-type patents.
We have confidentiality and noncompetition agreements with our
executive officers and certain other personnel.

     The processes and specialized equipment utilized in crystal
growth, infrared materials fabrication and infrared optical coatings as
developed by us are complex and difficult to duplicate.  However, there
can be no assurance that others will not develop or patent similar
technology or that all aspects of our proprietary technology will be
protected.  Others have obtained patents covering a variety of infrared
optical configurations and processes, and others could obtain patents
covering technology similar to our technology.  We may be required to
obtain licenses under such patents, and there can be no assurance that
we would be able to obtain such licenses, if required, on commercially
reasonable terms, or that claims regarding rights to technology will
not be asserted which may adversely affect our results of operations.
In addition, our research and development contracts with agencies of
the United States Government present a risk that project-specific
technology could be disclosed to competitors as contract reporting
requirements are fulfilled.

     We hold six registered trademarks: the II-VI INCORPORATED
(trademark) name; INFRAREADY OPTICS (trademark) for replacement optics
for industrial CO2 lasers; EPIREADY (trademark) for low surface damage
substrates for Mercury Cadmium Telluride epitaxy; and eV PRODUCTS
(trademark) for products manufactured by our eV PRODUCTS division;
LASER POWER CORPORATION (trademark) name; MP-5 (trademark) for low
absorption coating technology.  The trademarks are registered with the
United States Patent and Trademark Office, but not with any states.  We
are not aware of any interference or opposition to these trademarks in
any jurisdiction.

RISK FACTORS

We Depend on Highly Complex Manufacturing Processes Which Require
Products from Limited Sources of Supply

     We utilize high quality, optical grade ZnSe in the production of a
majority of our products.  We are a leading producer of ZnSe for our
internal use and for external sale.  The production of ZnSe is a
complex process requiring production in a highly controlled
environment.  A number of factors, including defective or contaminated
materials, could adversely affect our ability to achieve acceptable
manufacturing yields of high quality ZnSe.  ZnSe is available from only
one outside source where quantity and qualities may be limited.  The
unavailability of necessary amounts of high quality Zinc Selenide would
have a material adverse effect upon us.  In addition, in fiscal 1992
and 1993, we experienced fluctuations in our manufacturing yields which
affected our results of operations.  There can be no assurance that we
will not experience manufacturing yield inefficiencies which could have
a material adverse effect on our business, results of operations or
financial condition.

     We produce Hydrogen Selenide gas which is used in our production
of Zinc Selenide.  There are risks inherent in the production and
handling of such material.  Our inability to effectively handle
Hydrogen Selenide could require us to curtail our production of
Hydrogen Selenide.  Hydrogen Selenide can be obtained from one outside
source.  The cost of purchasing such material is significantly greater
than the cost of internal production.  As a result, purchasing a
substantial portion of such material from the outside source would
significantly increase our production costs of Zinc Selenide.
Therefore, our inability to internally produce Hydrogen Selenide could
have a material adverse effect on our business, results of operations
or financial condition.

     In addition, we utilize other high purity, relatively uncommon
materials and compounds to manufacture our products.  Failure of our
suppliers to deliver sufficient quantities of these necessary materials
on a timely basis could have a material adverse effect on our business,
results of operations or financial condition.

Our Business is Dependent on Other Cyclical Industries

     Our business is significantly dependent on the demand for products
produced by end users of industrial lasers.  Many of these end users
are in industries that historically have experienced a highly cyclical
demand for their products.  Therefore, as a result, demand for our
products and our results of operations are subject to cyclical
fluctuations.

Our Revenues are Subject to Potential Seasonal Fluctuations

     Due to our customers' buying patterns, particularly in Europe,
revenues for our first fiscal quarter ending in September could be
below those in the preceding quarter.  Our first fiscal quarter results
often are dependent upon the sales made in the last month of the
quarter.

We May Encounter Substantial Competition

     We may encounter substantial competition from other companies in
the same market, including established companies with substantial
resources.  Some of our competitors may have financial, technical,
marketing or other capabilities more extensive than ours and may be
able to respond more quickly than we can to new or emerging
technologies and other competitive pressures.  We may not be able to
compete successfully against our present or future competitors, and
competition may adversely affect our business, financial condition or
operating results.

International Sales Account for a Significant Portion of Our Revenues

     Sales to customers in countries other than the United States
accounted for approximately 37%, 49% and 47% of revenues during the
years ended June 30, 2001, 2000 and 1999, respectively.  We anticipate
that international sales will continue to account for a significant
portion of our revenues for the foreseeable future.  In addition, we
manufacture products in Singapore and China and maintain direct sales
offices in Japan, the UK and Belgium.  Sales and operations outside of
the United States are subject to certain inherent risks, including
fluctuations in the value of the U.S. dollar relative to foreign
currencies, tariffs, quotas, taxes and other market barriers, political
and economic instability, restrictions on the export or import of
technology, potentially limited intellectual property protection,
difficulties in staffing and managing international operations and
potentially adverse tax consequences.  There can be no assurance that
any of these factors will not have a material adverse effect on our
business, financial condition or results of operations.  In particular,
although our international sales, other than in Japan, Belgium  and the
UK, are denominated in U.S. dollars, currency exchange fluctuations in
countries where we do business could have a material adverse affect on
our business, financial condition or results of operations, by
rendering us less price-competitive than foreign manufacturers.  Our
sales in Japan are denominated in yen and, accordingly, are affected by
fluctuations in the dollar/yen currency exchange rates.  We generally
reduce our exposure to such fluctuations through forward exchange
agreements.  We do not engage in the speculative trading of financial
derivatives.  There can be no assurance, however, that our practices
will reduce or eliminate the risk of fluctuation in the dollar/yen
currency exchange rate.

Our Revenues May Suffer if General Economic Conditions Worsen

     Our revenues and earnings may be affected by general economic
factors, such as excessive inflation, currency fluctuations and
employment levels, resulting in a temporary or longer-term overall
decline in demand for our products.  Therefore, any significant
downturn or recession in the United States or other countries could
have a material adverse effect on our business, financial condition and
results of operations.

We May Expand Product Lines and Markets by Acquiring Other Businesses

     Our business strategy includes expanding our product lines and
markets through internal product development and acquisitions.  Any
acquisition may result in potentially dilutive issuances of equity
securities, the incurrence of debt and contingent liabilities, and
amortization expense related to intangible assets acquired, any of
which could have a material adverse affect on our business, financial
condition or results of operations.  In addition, acquired businesses
may be experiencing operating losses.  Any acquisition will involve
numerous risks, including difficulties in the assimilation of the
acquired company's operations and products, uncertainties associated
with operating in new markets and working with new customers, and the
potential loss of the acquired company's key employees.  In fiscal 1995
we acquired the Virgo Optics Division of Sandoz Chemicals Corporation.
In fiscal 1996 we acquired Lightening Optical Corporation.
Subsequently, these acquisitions were combined to form our VLOC
subsidiary.  In fiscal 2001 we acquired Laser Power Corporation.

Our Success Depends on New Products and Processes

     In order to meet our strategic objectives, we must continue to
develop, manufacture and market new products, develop new processes and
improve existing processes.  As a result, we expect to continue to make
significant investments in research and development and to continue to
consider from time to time the strategic acquisition of businesses,
products, or technologies complementary to our business.  Our success
in developing, introducing and selling new and enhanced products
depends upon a variety of factors including product selection, timely
and efficient completion of product design and development, timely and
efficient implementation of manufacturing and assembly processes,
effective sales and marketing, and product performance in the field.
There can be no assurance that we will be able to develop and introduce
new products or enhancements to our existing products and processes in
a manner which satisfies customer needs or achieves market acceptance.
The failure to do so could have a material adverse affect on our
ability to grow our business.

Failure to Keep Pace with Industry Developments May Adversely Affect
Our Operations

     We are engaged in industries which will be affected by future
developments.  The introduction of products or processes utilizing new
developments could render existing products or processes obsolete or
unmarketable.  Our continued success will depend upon our ability to
develop and introduce on a timely and cost-effective basis new
products, processes and applications that keep pace with developments
and address increasingly sophisticated customer requirements.  There
can be no assurance that we will be successful in identifying,
developing and marketing new products, applications and processes and
product or process enhancements, that we will not experience
difficulties that could delay or prevent the successful development,
introduction and marketing of product or process enhancements or new
products, applications or processes, or that our products, applications
or processes will adequately meet the requirements of the marketplace
and achieve market acceptance.  Our business, results of operations and
financial condition could be materially and adversely affected if we
were to incur delays in developing new products, applications or
processes or product or process enhancements or if we did not gain
market acceptance.

Exposure to Government Markets

     With the acquisition of Laser Power Corporation, sales to
customers in the defense industry have increased.  These customers in
turn generally contract with a governmental entity, typically the U.S.
government.  Most governmental programs are subject to funding approval
and can be modified or terminated with no warning upon the
determination of a legislative or administrative body.  The loss or
failure to obtain certain contracts or a loss of a major government
customer could have a material adverse effect on our business,
financial condition and results of operations.

Our Success Depends on the Ability to Retain Key Personnel

     We are highly dependent upon the experience and continuing
services of certain scientists, engineers, production and management
personnel.  Competition for the services of these personnel is intense,
and there can be no assurance that we will be able to retain or attract
the personnel necessary for our success.  The loss of the services of
our key personnel could have a material adverse affect on our business,
results of operations or financial condition.

There Are Limitations on the Protection of Our Intellectual Property

     We do not currently hold any material patents applicable to our
processes and rely on a combination of trade secret, copyright and
trademark laws and employee non-competition and nondisclosure
agreements to protect our intellectual property rights.  There can be
no assurance that the steps taken by us will be adequate to prevent
misappropriation of our technology.  Furthermore, there can be no
assurance that, in the future, third parties will not assert
infringement claims against us.  Asserting our rights or defending
against third-party claims could involve substantial expense, thus
materially and adversely affecting our business, results of operations
or financial condition.  In the event a third party were successful in
a claim that one of our processes infringed its proprietary rights, we
may have to pay substantial damages or royalties, or expend substantial
amounts in order to obtain a license or modify the process so that it
no longer infringes such proprietary rights, any of which could have an
adverse effect on our business, results of operations or financial
condition.

Our European Sales Rely On A Single Distributor

     A significant portion of our European sales not made by our
subsidiaries in the UK and Belgium have been made through a European
distributor.  This distributor also provides service and support to the
end users of our products.  Thus, a reduction in the sales efforts of
this distributor could adversely affect our European sales and our
ability to support the end users of our products.  There can be no
assurance that this distributor will continue to distribute, or to
distribute successfully, our products and, in such an event, our
business, results of operations and financial earnings could be
materially and adversely affected.

Our Stock Price May Fluctuate

     Future announcements concerning us, our competitors or customers,
quarterly variations in operating results, announcements of
technological innovations, the introduction of new products or changes
in product pricing policies by us or our competitors, seasonal or other
variations in anticipated or actual results of operations, changes in
earnings estimates by analysts or reports regarding our industries in
the financial press or investment advisory publications, among other
factors, could cause the market price of our stock to fluctuate
substantially.  In addition, stock prices may fluctuate widely for
reasons which may be unrelated to operating results.  These
fluctuations, as well as general economic, political and market
conditions such as recessions, military conflicts or market or market-
sector declines, may materially and adversely affect the market price
of our common stock.  In addition, any information concerning us,
including projections of future operating results, appearing in
investment advisory publications or on-line bulletin boards or
otherwise emanating from a source other than us could in the future
contribute to volatility in the market price of our common stock.

We Have Adopted Antitakeover Devices Which May Limit the Price that
Certain Investors May be Willing to Pay in the Future for Shares of Our
Common Stock

     Our articles of incorporation, by-laws and shareholder rights plan
contain provisions which could make us a less attractive target for a
hostile takeover or make it more difficult or discourage a merger
proposal, a tender offer or a proxy contest.  This could limit the
price that certain investors might be willing to pay in the future for
shares of our common stock.  The provisions include:

     - classification of the board of directors into three classes;

     - a procedure which requires shareholders or the board of
       directors to nominate directors in advance of a meeting to elect
       such directors;

     - the ability of the board of directors to issue additional shares
       of common stock or preferred stock without shareholder approval;
       and

     - certain provisions requiring supermajority approval (at least
       two-thirds of the votes cast by all shareholders entitled to
       vote thereon, voting together as a single class).

     - a formal shareholder rights plan designed to protect all
       corporate interests in the event the Company's Board of
       Directors and shareholders are confronted with an abusive or
       unfair takeover attempt.

     In addition, the Pennsylvania Business Corporation Law contains
provisions which may have the effect of delaying or preventing a change
in our control.

We Are Subject to Stringent Environmental Regulation

     We use or generate certain hazardous substances in our research
and manufacturing facilities.  We believe that our handling of such
substances is in material compliance with applicable local, state and
federal environmental, safety and health regulations at each operating
location.  We invest substantially in proper protective equipment,
process controls and specialized training to minimize risks to
employees, surrounding communities and the environment due to the
presence and handling of such hazardous substances.  We annually
conduct employee physical examinations and workplace air monitoring
regarding such substances.  When exposure problems or potential
exposure problems have been indicated, corrective actions have been
implemented and re-occurrence has been minimal or non-existent.  We do
not carry environmental impairment insurance.

     Relative to its generation and use of the extremely hazardous
substance Hydrogen Selenide, we have in place an emergency response
plan.  Special attention has been given to all procedures pertaining to
this gaseous material to minimize the chances of its accidental release
to the atmosphere.

     With respect to the production, use, storage and disposal of the
low-level radioactive material Thorium Fluoride, our facilities and
procedures have been inspected and licensed by the Nuclear Regulatory
Commission.  This material is utilized in our thin-film coatings.
Thorium bearing by-products are collected and shipped as solid waste to
a government-approved low-level radioactive waste disposal site in
Clive, Utah.

     The generation, use, collection, storage and disposal of all other
hazardous by-products, such as suspended solids containing heavy metals
or airborne particulates, are believed by us to be in material
compliance with regulations.  We believe that all of the permits and
licenses required for operation of our business are in place.  Although
we do not know of any material environmental, safety or health problems
in its properties or processes, there can be no assurance that problems
will not develop in the future which would have a materially adverse
effect on us.

Some Laser Systems Are Complex in Design and May Contain Defects that
Are Not Detected Until Deployed Which Could Increase Our Costs and/or
Reduce Our Revenues

     Laser systems are inherently complex in design and require ongoing
regular maintenance.  The manufacture of lasers, laser products and
systems involves a highly complex and precise process.  As a result of
the technical complexity of our products, changes in our or our
suppliers' manufacturing processes or in the use of defective or
contaminated materials by us or our suppliers could result in a
material adverse effect on our ability to achieve acceptable
manufacturing yields and product reliability.  To the extent that we do
not achieve such yields or product reliability, our business, operating
results, financial condition and customer relationships could be
adversely affected.  Our customers may discover defects in our products
after the products have been fully deployed and operated under peak
stress conditions.  In addition, some of our products are combined with
products from other vendors, which may contain defects.  Should
problems occur, it may be difficult to identify the source of the
problem.  If we are unable to fix defects or other problems, we could
experience, among other things:

     - loss of customers;
     - increased costs of product returns and warranty expenses;
     - damage to our brand reputation;
     - failure to attract new customers or achieve market acceptance;
     - diversion of development and engineering resources; and
     - legal action by our customers.

     The occurrence of any one or more of the foregoing factors could
seriously harm our business or financial condition.
