Zinc Sulphide


Zinc Sulphide (ZnS) is a widely-used IR transmitting material used for windows, lenses and other optical components and is sometimes referred to as Cleartran™. The material transmits at about 50% between 0.4 -12μm before dropping off to zero transmission at around 15μm. Its low absorbance in the IR spectrum makes it suitable for CO2 lasers operating at 10.6μm. Zinc Sulphide has a pale yellow appearance and a hardness of HK160. Although the material is resistant to thermal shock, it is not recommended for harsh environments.
