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. The high hardness, good thermal conductivity, and insoluble in water features make germanium optics widely used in infrared imaging systems and infrared spectrometer systems. The mechanical properties and thermal conductivity of germanium are good; in the range of 10.6 µm wavelength, germanium lens' absorption is very small, which makes it an ideal material for a CO2 laser lens, window, and output coupler. Germanium (Ge) substrate materials were also used to make all kinds of infrared filters.

How Do Germanium Optics Work?

Germanium optical windows 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 glass Lens, 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.
