Optics

Calcium Fluoride

Calcium Fluoride has widespread IR

applications and is also useful in the

UV and as UV Excimer laser windows.

Degradation due to moisture in the

atmosphere is minimal and polished

surfaces may be expected to withstand

several years exposure to normal

atmospheric conditions. Low solubility

and wide transmission makes this

material useful for many applications.

Special AR coated optics can be

offered on request.

Zinc Selenide

Zinc Selenide optics are used widely as

IR windows. Zinc Selenide is one of the

materials of choice for CO2 laser optics

operating at 10.6μm. Optics with antireflective

coatings can also be offered

on request.
