ZnS has a lower cost relative to ZnSe and ZnS MS

ZnS MultiSpectral Infrared’s zinc sulfide material treated by a hot isostatic press (HIP) process. This optical material transmits from 0.4 to 12 microns.

ZINC SELENIDE Material is the material of choice for optical components in high-powered CO2 lasers due to its low bulk absorption at 10.6 microns. I
