II-VI Incorporated was founded in 1971 to supply better materials to infrared optics producers. Initially starting with cadmium telluride, II-VI gravitated to producing zinc selenide and zinc sulfide during the 1980s. II-VI’s vertical integration, from materials growth through precision optics manufacturing, positions the company as the leader in CO2 laser optics.
Today, II-VI Infrared is the world’s leading producer of ZnSe material. Our ZnS Regular and ZnS MultiSpectral materials are used in a growing number of infrared systems both domestically and abroad.
