    Product Parameter

    v CVD zinc selenide (ZnSe) is a chemical inert material with high purity, strong environmental adaptability, and easy processing. Its optical transmission loss is small and has good penetration. It is the prioritized chosen material for high power CO2 laser optical components. Since the refractive index of this material is well uniform and consistent, it is also ideal for making protective window and infrared optics in FLIR thermal imaging system. At the same time, the material is also widely used in making window and lens for medical instrument, the industrial thermal radiation measuring instrument and the infrared spectrometer. Zinc selenide is easy to be scratched, which is not suitable for using in harsh environments (Knoop hardness is only 120). Its transmission spectrum ranges from 120nm to 7000nm and is usually used in thermal imaging systems, Aerospace optical systems and excimer laser optical systems.
