Product Details
CVD zinc selenide is a chemically inert material with high purity, strong environmental adaptability, and ease of processing. It has low optical transmission loss and excellent transparency. It is a high-power CO2 laser optical componentmaterial Due to its uniform and consistent refractive index, this material is also an ideal material for protecting windows and optical components in forward-looking infrared (FLIR) thermal imaging systems. Meanwhile, this material is widely used in windows and lenses in medical and thermal radiation measuring instruments, as well as infrared spectrometers.
