Overview
Germanium single crystal has high hardness, good thermal conductivity, insoluble in water, and a transmission band of 2-12 μm. It is a very commonly used infrared optical material. Currently widely used in infrared imaging systems and infrared spectrometer systems. Germanium single crystal is also used as the base material for various infrared filters. High-purity germanium single crystal has a high refractive index, is transparent to infrared rays, and does not transmit visible light and ultraviolet rays. It can be used as a germanium window, prism or lens that specifically transmits infrared light. Germanium's ability to absorb light continues to strengthen as the temperature rises. Above 100 degrees Celsius, it has a significant impact on the light transmittance, seriously affecting the performance of the optical system. Germanium components are usually coated with anti-reflective coatings due to their high surface reflectivity. 3~12μm coated germanium windows are used in mid-infrared and multispectral applications, and 8~12μm germanium windows are usually used in thermal imaging and infrared imaging systems
