Infrared Optical ZnS Window Coated Customized

The refractive index of Zinc sulfide (ZnS) is uniform and consistent. lt has a good image transmission performance in 8000 nm-12000 nm wave band. The material also has a high transmittance in mid-infrared, but with the shortening of wavelength, absorption and scattering will increase.
