ZnS (Zinc Sulphide Multispectral, CVD)

ZnS Multispectral (water-clear) is used for IR windows and lenses in the thermal band (8 to 14 μm) where maximum transmission and lowest absorption is required. Also selected for use where visible alignment is an advantage.

ZnSe (Zinc Selenide)

ZnSe is used widely for IR components, windows and lenses, and for spectroscopic ATR prisms. Zinc Selenide is one of the materials of choice for CO2 laser optics operating at 10.6 microns.
