             VEECO REPORTS FOURTH QUARTER AND YEAR-END 2003 RESULTS

Woodbury, NY, February 6, 2004 -Veeco Instruments Inc. (Nasdaq: VECO) today
announced its financial results for the fourth quarter and year ended December

Emcore Corporation and the purchase of Advanced Imaging, Inc., ("Aii") a leading
manufacturer of precision lapping equipment for the data storage industry,
referred to collectively as the "acquisitions" below.

HIGHLIGHTS

     Veeco's fourth quarter 2003 sales were $76.9 million, up 22% sequentially
from the $63.1 million reported in the third quarter of 2003. Veeco reported a
net loss of $4.8 million, or a loss of $0.16 per share. Earnings excluding

(See tables for explanation of purchase accounting and reconciliation to GAAP
loss).

earnings excluding certain charges between $0.00 and $0.03 per diluted share.

     The Company's fourth quarter 2003 bookings were $96.8 million, up 51%
sequentially from the third quarter, including bookings from the acquired
companies post-acquisition. Veeco's fourth quarter book-to-bill was 1.26 to 1.

31% sequentially from $64.0 million reported in the third quarter of 2003.
Veeco's fourth quarter order guidance (without acquisitions) was $64-$70
million. Veeco's year-ending backlog was $124.4 million.

     Edward H. Braun, Veeco's Chairman and Chief Executive Officer, commented,
"Veeco's fourth quarter orders, revenues and EBITA improved both sequentially
and year-over-year. Order strength reflected a broad industry upturn across all
of our markets and in all geographic regions. Capacity and technology drivers
were evident in semiconductor, data storage, wireless, compound semiconductor
and scientific research. Fourth quarter orders of $96.8 million (up 51%
sequentially) were Veeco's strongest overall orders in ten quarters. Fourth
quarter revenue of $76.9 million was up 22% sequentially."

     "The November 2003 acquisitions of TurboDisc MOCVD and Advanced Imaging
Inc.'s precision lapping technologies allow us to significantly broaden our
product and technology offerings to Veeco's core markets in 2004," commented Mr.
Braun.

     Mr. Braun commented on Veeco's full year 2003, adding, "Overall 2003 was a
challenging year for the equipment industry and for our customers. Veeco's 2003
sales of $279.3 million were down 7% from 2002, while orders of $297.6 were up a
modest 3%. Significant 2003 focus on cost reduction and profitability resulted
in improved gross margins (up 2.2 points) to 46.0% (exclusive of purchase
accounting adjustments), and 2003 EBITA (earnings excluding certain charges
before interest, income taxes and amortization) was $13.0 million, up from $1.3
million in 2002 despite the decrease in revenue. Veeco also generated $21.8
million of cash from operations during 2003 and our balance sheet remains strong
with $106.8 million in cash after the completion of acquisitions."

VEECO'S OUTLOOK

     Mr. Braun commented, "Industry market conditions improved dramatically in
the fourth quarter, and we appear to be at the start of a sustainable recovery
cycle after two years of historically low capex investment by our customers.
Veeco's diversification strategy should serve us well as multiple Veeco markets
are forecasted to experience 2004 growth."

     "We intend to work closely with our key customers to be aligned with their
technology roadmaps and capacity planning requirements including: the continued
80GB production ramp and 120GB disk drive development programs, 90nm and 300mm
ramps in semiconductor, growth in high brightness light-emitting diodes
(HB-LEDs) for backlighting of color displays, RF devices and other
wireless/lighting applications, and continued use of our atomic force
microscopes in nanoscience research." Mr. Braun concluded, "Veeco's goal is to
achieve higher levels of revenue and profitability in 2004 through a combination
of improved business conditions, a continued focus on cost control, and a
broadened product line of key enabling process equipment and metrology
technologies."

     Veeco currently forecasts that first quarter 2004 bookings and revenue will
increase approximately 10% sequentially. First quarter 2004 orders are
forecasted to be in the range of $105 to $109 million and sales in the range of
$84 to $88 million. Veeco's book-to-bill is forecasted to remain at
approximately 1.2 to 1. The Company currently forecasts that it will incur a net
loss between ($0.09 and $0.05) per share on a GAAP basis and will earn between
$0.05 and $0.09 per share, excluding amortization of $5.0 million and purchase
accounting adjustments related to the acquisitions of $1.9 million, using a 35%
tax rate.
