ZnSe Material

ZnSe is a preferred material for lenses, windows, output couplers and beam expanders for its low absorptivity at infrared
wavelengths and its visible transmission. For high-power applications, it’s critical that the material bulk absorption and
internal defect structure be carefully controlled, that minimum-damage polishing technology be employed, and the
highest quality optical thin-film coatings are used. The material absorption is verified by CO2 laser vacuum calorimetry.
Our quality assurance department provides testing and specific optics certification on request.

ZnSe is non-hygroscopic and chemically stable, unless treated with strong acids. It’s safe to use in most industrial,
field, and laboratory environments.
