            Dynasil Corporation of America Reports
              Fiscal Year 2011 Financial Results
          - Revenue Increases 9 Percent to $47 Million
   - Company Posts Net Income of $1.4 Million,  EPS of $0.08
- Company to Host Earnings Conference Call at 5:00 p.m. (ET) Today

Watertown, MA, December 29, 2011 - Dynasil Corporation of America (NASDAQ:
DYSL), a leading developer of sensing, detection and analysis technology for
homeland security, medical and industrial applications, today reported
financial results for fiscal year ended September 30, 2011.

Revenue for fiscal 2011 increased to $47.0 million compared with $43.0 million
in fiscal 2010.  Contract Research segment revenue increased to $24.9 million
from $23.1 million in fiscal 2010. The Company's renamed Products & Technology
segment (previously called "Optics/Photonics, Products & Instruments") posted
revenue of $22.1 million, up from $19.9 million a year earlier.

Net income for the 12 months ended September 30, 2011 was $1.4 million, or
$0.08 per diluted share, compared with $3.2 million, or $0.22 per diluted
share, in fiscal 2010.  Lower net income in the 2011 period resulted from
higher selling, general and administrative expenses and increased investment
in corporate growth initiatives, partially offset by Research &
Experimentation (R&E) Tax Credits. For fiscal year 2011, the Company had an
income tax expense of $293,198 compared with an income tax expense of $929,661
for fiscal year 2010.  The significant difference primarily resulted from
state and federal R&E tax credits of approximately $1.5 million in fiscal
2011, partially offset by the required deferred tax liability recorded for the
tax effects of book/tax differences related to Property, Plant and Equipment,
Goodwill, and Intangible Assets.

"Dynasil delivered 9 percent revenue growth in 2011, with gains in both
business segments despite a challenging economic environment," said Steven
Ruggieri, the Company's president and chief executive officer.   "Our Contract
Research segment grew $1.8 million, or nearly 8 percent, from fiscal 2010,
reflecting robust business with key federal customers including the U.S.
Department of Homeland Security and the U.S. Department of Energy.  Our
Products & Technology segment grew more than $2 million, or 11 percent, from
the year-earlier period, primarily as a result of our acquisition of Hilger
Crystals in the fourth quarter of fiscal 2010."




Product Pipeline

"During the fourth quarter of 2011 we began shipping our dual-mode radiation
detectors to OEM customers for beta testing, and we remain on track to begin
generating revenue from this program in 2012," Ruggieri said. "Our dual-mode
technology represents the first in a planned pipeline of scintillation crystal
products capable of advanced radiation detection for markets including
homeland security, baggage screening and energy."

"Our product pipeline also includes sensors for non destructive testing,
radiation dosimeters based on technologies developed at our RMD Research
business unit and thin film digital X-rays," Ruggieri continued. "In addition,
we are testing and evaluating three  of the biomedical technologies acquired
earlier this year from Dr. Daniel Ericson.  While development is still in the
early stages, we believe that  these technologies have commercial potential."

Recent Highlights

     .    Dynasil promoted Kanai S. Shah, Ph.D., Vice President of Research and
     leader of the Materials Science Group, to President of RMD Research, the
     Company's research business unit, beginning in December. Dr. Shah, 50,
     joined RMD in 1985 as a Staff Scientist. He became Director of Research
     in 2002 and Vice President of Research in 2009. He has been responsible
     for new semiconductor and scintillator development at RMD for more than
     a decade.

     .    RMD Research received contracts totaling $3.65 million from the
     Department of Homeland Security's Domestic Nuclear Detection Office
     (DNDO). These contracts provide funded research and development of gamma
     and neutron radiation detectors capable of identifying illicit nuclear
     materials. The contracts consist of $2.15 million under the DNDO's
     Exploratory Research Program (ERP) and $1.5 million under the Small
     Business Innovation Research (SBIR) program. Earlier this month, the
     U.S. House and Senate negotiated a deal to reauthorize the SBIR program
     for an additional six years.

"In fiscal 2011 we made good progress in expanding our product pipeline and
diversifying our contract research business," Ruggieri said. "In the coming
quarters, we expect to have a product realization process in place designed to
support the evaluation, assessment, development and commercialization of our
technologies. We have a number of exciting milestones to look forward to in
2012, and we believe that we are well positioned for continued growth."
