Optical Windows are flat, plane-parallel plates that are often used
as protective barriers for electronic sensors or detectors from
outside environments. Optical Windows should be selected based on
the material transmission or mechanical properties of the
substrate. Optical Windows do not cause change in the magnification
of a system. GIAI Optics’ Optical Windows are offered in a variety
of substrates, such as Germanium (Ge), Silicon (Si), N-BK7, UV
Fused Silica, Zinc Selenide (ZnSe), or Potassium Bromide (KBr).
Multiple anti-reflection coating options are available for the
Ultraviolet (UV), visible, or Infrared (IR).
Optical Diffusers are used to control the diffuse area of
illumination by evenly diffusing the light source as it passes
through the Optical Diffuser. GIAI Optics offers Holographic, Opal,
or Ground Glass Diffusers in a variety of sizes or diffusing
angles. Holographic Diffusers offer superior transmission
efficiency compared to glass diffusers. Optical or Ground Glass
Diffusers are cost-sensitive alternatives.
BOROFLOAT® Borosilicate Windows are ideal for high temperature and
harsh environment applications. Unlike common borosilicate that is
drawn flat, BOROFLOAT® is produced by a float technique that yields
superior surface accuracy — typically 4 - 6λ per inch. BOROFLOAT®
is about three times more resistant to thermal shock than standard
soda lime glass.
