Germanium lens is an optical lens made of polished germanium. These lenses are durable, corrosion-resistant, and suitable for harsh environments and applications that are often exposed to the elements. Germanium lens has a high refractive index, which is the highest among existing infrared transmitters. Because of its low dispersion, it also shows minimum chromatic aberration. Due to these characteristics, the germanium lens is an ideal choice for infrared applications. Other applications include thermal imaging systems and precision analytical instruments, which can be used in harsh environments.

Germanium has many special properties. It has wide and important applications in semiconductors, aerospace measurement and control, nuclear physics detection, optical fiber communication, infrared optics, solar cells, chemical catalysts, biomedicine, and other fields. It is an important strategic resource. In the electronic industry, alloy pretreatment, in the optical industry, can also be used as a catalyst.
High-purity germanium is a semiconductor material. It can be extracted from high-purity germanium oxide by reduction and smelting technology. Germanium single crystal with a small amount of specific impurities in its composition can be used to manufacture various transistors, rectifiers and other devices.
Germanium single crystal can be used as a transistor and is the first generation of transistor material. Germanium materials are used for radiation detectors and thermoelectric materials. High-purity germanium single crystal has a high refractive index, is transparent to infrared, and does not penetrate visible light and ultraviolet light. It can be used as a germanium window, prism, or lens that specifically transmits infrared light.
The refractive index of simple germanium is very high. It is only transparent to infrared light, but not transparent to visible light and ultraviolet light. Therefore, military observers such as infrared night vision instruments use pure germanium to make lenses. Germanium and niobium compounds are superconducting materials. Germanium dioxide is a catalyst for polymerization. The glass containing germanium dioxide has a high refractive index and dispersion performance and can be used as a wide-angle camera and microscope lens. Germanium trichloride is also a new additive for optical fiber materials.
High-purity germanium single crystal has a high refractive index, is transparent to infrared, and does not penetrate visible light and ultraviolet light. It can be used as a germanium window, prism, or lens that specifically transmits infrared light.
The absorption capacity of germanium to light is continuously strengthened with the rise of temperature. Above 100 ℃, it will have a significant impact on the light transmittance and seriously affect the performance of the optical system Germanium elements are usually coated with the antireflection film due to their high reflectivity.
Germanium lens processing can be easily divided into three types: commercial, precision, and high-precision. Please select the appropriate type according to the actual application.
