Description
GENERAL INFORMATION
Zinc sulfide is mainly used for IR optical applications (e.g., AR coatings on Ge, thermal imaging) and can be evaporated easily from resistively heated boats resulting in durable coatings. It has a broad transmission range from 400 nm up to 14 µm. ZnS can be applied as high refractive index material in the VIS-NIR range in combination with fluorides such as MgF2, although in many of these applications it nowadays has been being replaced by the harder oxidic materials such as TiO2.
