GENERAL INFORMATION Zinc selenide has found widespread use in infrared optics due to its very broad transmission range from about 0.5 µm to about 14 µm and can be applied for IR optical thin film coatings made by vapor deposition. AREAS OF APPLICATION
Multilayer coatings mainly in the IR spectral range such as mirrors, beam splitters and AR (e.g., on Ge and ZnSe)
