Features | Various crystals are widely used in medium wave infrared detectors and infraredthermal imagers, among which silicon (SI) and germanium (GE) are the most widely used infrared optical materials. They have thecharacteristics of metallic luster, hard and brittle, high refractive index, small dispersion, opaque in visible light band, butgood transmittance in infrared band (3 ~ 5um).Due to the small proportion, light weight and high transmittance of monocrystallinesilicon in the middle wave infrared optical system, Si is widely used as the material of optical lens and infrared window in theoptical system. |
