Dow Electronic Materials vapor deposited zinc selenide,CVD ZINC
SELENIDE Material, is the material of choice for optical components in
high-powered CO2 lasers due to its low bulk absorption at 10.6 microns. Its
index of refraction homogeneity and uniformity offer 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.
Dow Electronic Materials CVD ZINC SELENIDE Material 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. Dow Electronic Materials' CVD ZINC SELENIDE Material is
also available as an evaporative source material. It is supplied in specified
lump sizes (2–20 mm), which are hand selected to minimize surface
contamination and to be free from saw cut, abraded or polished edges
