ZnSe Optics

02 Apr 2025

Zinc Selenide is one of the materials of choice for CO2 laser optics operating at 10.6 microns.  Its index of refraction homogeneity and uniformity offers excellent optical performance for use as protective windows or optical elements in high resolution forward looking infrared (FLIR) thermal imaging equipment. This material has also been used as small windows and lenses in medical and industrial applications, such as thermometry and spectroscopy.
