Zinc Selenide
CVD ZINC SELENIDE
Chemically vapor deposited ZINC SELENIDE (CVD ZnSe) is the material of choice for use as optical components in
high powered CO2 lasers due to its low bulk absorption 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.
Advanced Materials’ CVD ZINC SELENIDE is chemically inert, non-hygroscopic, highly pure, theoretically dense,
and easily machined. It has extremely low bulk losses due to absorption and scatter, has a high resistance to
thermal shock, and is stable in virtually all environments.
Circular blanks and sheet material are available in stock to meet your most urgent delivery requirements. Custom
diameters, rectangles, CNC-profiled blanks, generated lens blanks, prisms, and near-net shape domes can also be
made to your specifications.
Advanced Materials’ CVD ZINC SELENIDE is also available as an evaporative source material. It is supplied in
specified lump sizes (2-20 mm), which to minimize surface contamination, are hand selected to be free from saw
cut, abraded or polished edges.
