Zinc sulfide is a relevant material for infra red application in the 3-10 microns band.

Litterature repports only a few countries in the world master this CVD technology. MPA Industrie system is suitable for domes and plates production.

ZnSe can be achieved by the same method. The example shows a rough ZnS dome after deposition. Diameter is 180 mm and thichness 6 mm. After polishing, HIP and AR coating 95 % transmission is reached.
