| The
Asphere Benefit
It
is widely known that
there are many
substantial advantages to
use aspheres in any
optical system. Aspheres
reduce the number of
optical surfaces while
achieving more highly
corrected imaging
performance. Optical
designers are aware that
aspheric surfaces
eliminate aberrations and
distortions in more
compact lower mass
optical systems.
Aspheres
are widely used in IR
optical systems due to
the advances in Diamond-
Turning technology which
makes it possible to
routinely cut precision
aspheric surfaces in IR
materials.
However,
for visible optics,
designers continue to be
reluctant to take
advantage of the inherent
benefits of aspheres in
imaging systems. The many
challenges that optics
manufacturers have had to
overcome while polishing
glass aspheric surfaces
have left designers with
little confidence that
precision glass aspheres
can be production volume,
within specification,
within budget and on
time.
Over
the past decade our
maturing understanding of
technology and process
has lead to the emergence
of new
tools which make it
possible for us to
routinely produce a wide
variety of complex glass
aspheres. At Precision
Asphere LLC we pride
ourselves in the ability
to produce affordable
high precision glass
aspheres that give our
customers a
competitive advantage.
