CVD zinc selenide window plate

CVD zinc sulfide is a chemically inert material with high purity, insoluble in water, moderate density and easy processing. It is widely used in the manufacture of infrared window, fairing and infrared optical components. Like zinc selenide (ZnSe), zinc sulfide (ZnS) is also a material with good refractive index uniformity and consistency, which has good image transmission performance in the 8000nm-12000nm band. The material also has high transmittance in the mid-infrared band, but the absorption and scattering are enhanced as the wavelength gets shorter. Compared with zinc selenide (ZnSe), zinc sulfide is low price, high hardness, fracture strength is twice that of zinc selenide, strong resistance to harsh environment, non-chang suitable for fairing and aircraft infrared window.
