Zinc Selenide (ZnSe)

Zinc Selenide (ZnSe) Data Sheet

Application
CO2 laser components, infrared spectroscopy, imaging system, IRpyrometers, surveillance and detection systems.

Product and technology advantages
Project participants have been developing the technology for
high-quality CVD-ZnSe production since 1983. Over 120 publications were published on issues
associated with zinc selenide and zinc sulfide, four patents of the Russian Federation were received, there are five know-hows.
Based on those researches the technology of FLIR grade and Laser grade material has been developed.
