ZnSe Window

ZnSe Window

The transmission range of Zinc Selenide ZnSe-CVD is around 0.5 - 20 µm. The refractive index of ZnSe is near 2.4. Zinc Selenide has a very low absorbtion coefficient and is used extensively for high power infrared laser optic. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined.

CVD ZnSe is widely used for high power CO2 laser at 10.6µm, used as protective windows or optical elements in FLIR (forward looking infrared) thermal imaging equipment, optics for medical and industrial applications (optical plane parallel windows (plates, disks, blanks), wedged windows, optical meniscus, spherical and cylindrical lenses, prisms, resonator mirrors of CO2 laser). 

Wuhan Especial Optic can customize high-precision zinc selenide windows with a maximum diameter of 380mm and a thickness of 1-30mm. Shape is typically circular, rectangular, wedged, stepped, or customized as needed. Moreover, we also provide coating services: AR coating, broadband BBAR coating or beamsplitter coating.
