is used for optical windows, lenses, mirrors, prisms and optical blanks,
plates, disks, sheets, slabs particularly for infrared applications.
Selenide (ZnSe) - transparent in wide spectral range from yellow (visible)
to far IR.
material is a chemically inert, non-hygroscopic and highly pure product
that is very effective in many optical applications due to its extremely
low bulk losses, high resistance to thermal shock and stability in
virtually all environments, easily machined.
obtain superior transmittance, ZnSe crystals are grown by Chemical Vapor
Deposition process .
Selenide is polycrystalline material, demonstrates superior CO2 laser
transmittance and is employed in the transmission optical components used
in CO2 laser processing.
