Description:

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.
