Zinc selenide windows: With their low absorption coefficient, high thermal shock resistance, minimal optical transmission loss, and excellent light transmission, they are widely used in high-power CO2 laser systems. Due to their wide wavelength range (600nm-18000nm) and excellent refractive index uniformity, they are ideal for many infrared (FLIR) thermal imaging systems and mid-wave infrared (MWIR) to infrared applications. They are also used in windows, lenses, and prisms in medical and industrial thermal radiation meters and infrared spectrometers.
