A Tutorial on Infrared Optical Materials M.R. Burgener

Zinc Selenide (ZnSe) Zinc Selenide is very similar to Zinc Sulfide. As can be seen in Figure 4 Zinc Selenide is a broadband material supporting imaging. Due to the fact that Zinc Selenide is only about half as hard as Zinc Sulfide and low transmission when uncoated it is usually coated to support MWIR and LWIR imaging. It is an expensive material.
