Zinc Sulfide Window (ZnS) Description

Zinc Sulfide Window (ZnS) is an infrared optical window/substrate material with excellent performance. It has a transmission range of 3-13um and is not easy to deflect. It is the most commonly used mid- and far-infrared window material. Zinc Sulfide (ZnS) has good refractive index uniformity and consistency and has good image transmission performance in the 8-12μm band, but some parts begin to absorb after 10um. The transmittance is higher in the mid-infrared band, and as the wavelength becomes shorter, absorption and scattering increase. Zinc sulfide (ZnS) has strong resistance to harsh environments, high hardness, and twice the breaking strength of zinc selenide (ZnS).
