Zinc Selenide Windows For Thermal Imaging

Zinc Selenide Windows For CO2 Lasers and Thermal Imaging

ZnSe is used as a material for production of optical elements (windows, lenses, prisms) for IR range including the passive laser optics elements. CVD - ZnSe is extremely uniform in structure; it has superior optical transmission with extremely low bulk losses from scatter and absorption.

CVD - ZnSe is the first choice for high power laser windows and multispectral application with useful transmitting range of 0.5 - 19 mm. It offers excellent imaging characteristics, high resistance to thermal shock, and is stable in virtually all operating environments. This material is soft and non-hygroscopic.
