Germanium (Ge) crystal is a chemical inert material, its useful transmission range is from 2 to 12 µm, which is most commonly used in infrared optical components. Its high hardness, good thermal conductivity, insoluble in water features, makes it widely used in infrared imaging system and infrared spectrometer system. The mechanical properties and thermal conductivity of germanium is good, in the range of 10.6 µm wavelength, its absorption is very small, which is the ideal material for CO2 laser lens, window and output coupler. Germanium (Ge) substrate materials were also used to make all kinds of infrared filter.

How Do Germanium Optics Work?

Germanium optics work based on the unique properties of germanium, a semiconductor material. Germanium has a high refractive index and excellent transmission in the infrared region, making it ideal for infrared optics. When light passes through germanium optics, it undergoes minimal absorption and dispersion, allowing for efficient transmission and focusing of infrared radiation. This makes germanium optics crucial in various applications such as thermal imaging, spectroscopy, and infrared sensing.
