In 1971, II-VI Incorporated began by exclusively producing the highest-quality cadmium telluride (CdTe) material available for manufacturing high-power industrial CO2 laser optics. Today, we have diversified into producing zinc selenide (ZnSe) material, as well as into numerous business units including laser tools for materials processing (HIGHYAG); near-infrared optics, YAG components, and telecommunications components (VLOC); fiber optics, projection and display optics, DPSS laser, crystal materials, and other photonics products (Photop); defense and aerospace optics (Exotic Electro-Optics); tellurium and selenium products (PRM); thermoelectric cooling devices (Marlow Industries); silicon carbide (II-VI WBG); and advanced materials development (II-VI AMDC). Given this diversity of II-VI Incorporated's business units, we have thus christened our original IR materials and optics business unit II-VI Infrared.

As II-VI Incorporated continues to grow, II-VI Infrared focuses on the companys original, industry-leading products: infrared and CO2 laser optics and materials. And thanks to decades of innovation in ZnSe and zinc sulfide (ZnS) materials processing, thin-film coating, precision diamond-turning, and finished optics fabrication, II-VI Infrared is the world leader in CO2 laser optics, delivering an unbeatable combination of innovation, quality, and experience. II-VI Infrared also delivers the largest vertically integrated CO2 laser optics manufacturing process -- from raw materials to finished coated products -- in the world.
