      Dynasil Announces Second Quarter Fiscal Year 2007 Results

WEST BERLIN, N.J. - May 14, 2007 - Dynasil Corporation of America
(OTCBB: DYSL.OB), announced results of operations for the quarter
ended March 31, 2007.  Dynasil is a manufacturer of photonic products
including optical materials, components, coatings and specialized sub-
systems.  We fabricate optical blanks from synthetic fused silica and
other optical materials for the laser, semi-conductor, aerospace and
optical instrument industries. Through our subsidiary, Optometrics
Corporation, we are a worldwide supplier of optical components
including diffraction gratings, thin film filters, laser optics,
monochromators, and specialized optical sub-systems.  On October 2,
2006, we acquired 100% of the stock of Evaporated Metal Films
Corporation ("EMF") in Ithaca, NY.  EMF provides optical thin-film
coatings for a broad range of application markets including display
systems, optical instruments, satellite communications and lighting.
This is the second quarter that includes EMF.

Revenues  for  the quarter ended March 31, 2007 were  $3,003,216,  an
increase  of  80% over revenues of $1,665,496 for the  quarter  ended
March  31, 2006. The net profit for the quarter ended March 31,  2007
was  $112,229,  or  a positive $.02 per share, compared  with  a  net
profit of $81,881, or $.02 per share, for the quarter ended March 31,
2006.  Excluding  the impact of the EMF acquisition  and  $11,366  of
stock option expense, revenues for our historical businesses were  up
39%  and net income was up 208% from $81,881 to $251,866 compared  to
the  three  months  ended  March 31,  2006.   Strong  revenue  growth
combined  with continued process improvements drove those significant
gains.  As  anticipated, transitional and process  improvement  costs
resulted  in a loss at EMF for its second quarter with Dynasil.   The
EMF  loss  offset  the  substantial improvements  in  our  historical
businesses.    Management is clearly focused on the  EMF  initiatives
required  to  show  continued improvement  in  2007  and  to  deliver
profitable  results  for  fiscal year 2008.   During  Quarter  2,  we
significantly improved manufacturing yields and reduced  downtime  as
we develop the disciplined processes required for EMF to consistently
execute with strong quality, service, and cost performance.

Revenues for the 6 months ended March 31, 2007 were $5,539,512, an
increase of 72% over revenues of $3,213,536 for the 6 months ended
March 31, 2006.  The net profit for the 6 months ended March 31, 2007
was $135,128, or $0.02 per share, compared with a net profit of
$107,306, or $0.02 per share, for the 6 months ended March 31, 2006.
Excluding the impact of the EMF acquisition and $11,366 of stock
option expense, revenues for our historical businesses were up 31%
and net income was up 256% from $107,306 to $381,866 compared to the
six months ended March 31, 2006.

 "We are pleased with the second quarter net income increases of 208%
for our historical business and we are showing progress at EMF. We
have a very clear focus on the EMF improvements required to make it
profitable." said Craig T. Dunham, President and CEO.  "Achieving 39%
organic growth and the EMF operational improvements are important
milestones towards executing our strategy of profitable growth in our
photonic businesses."
