ZnSe Optics

CVD zinc selenide (ZnSe) is a chemical inert material with high purity, strong environmental adaptabilitly, and easy processing. Its optical transmission loss is small and has good penetration. ZnSe Optics are the prioritized chosen materials for hich power CO2 laseroptical components. Since the reractive index ot this material is wel unitorm and consistent, ZnSe IR is also idea for makinaprotective window and infrared optics in FLlR thermal imaging system, At the same time, the material is also widely used in making window and electromechanical instruments, the intuitive thermal radiation measuring instrument, and the intrarecspectrometer. ZnSe Optics are easy to scratch, which are not suitable for use in harsh environments (Knoop hardness is only 120). The transmission spectrum ranges from 120 nm to 7000 nm and ZnSe IR is usually used in thermal imaging systems, aerospace optical systems and excimer laser optical systems.
