Zinc Sulphide Lens - Ir Transmitting Material For Co2 Lasers, Low Absorbance And High Hardness

We make and supply of Zinc Sulphide Lense from Navi Mumbai, Maharashtra, India. Mechvac supply a range of quality Zinc Sulphide optical components including Zinc Sulphide lenses. Zinc Sulphide (ZnS) is a widely-used IR transmitting material used for windows, lenses and other optical components. The material transmits at about 50% between 0.4 -12m before dropping off to zero transmission at around 15m. Its low absorbance in the IR spectrum makes it suitable for CO2 lasers operating at 10.6m. 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. Zinc Selenide is used in the form of optical windows in FLIR (Forward Looking Infrared) systems, as meniscus, spherical or cylindrical lenses and as resonator windows in CO2 lasers.
