Germanium (Ge) Windows are parallel plane panels commonly used as protective windows for electronic sensors or detectors of the external environment. When selecting a window, attention should be paid to the window material, transmittance and transmission band, surface shape, smoothness, parallelism and other parameters.

Germanium is an optical glass material commonly used in the infrared band. The transmission band is 2.0-16μm. It has the characteristics of high refractive index and high Knoop hardness. Germanium is inert to air, water, acid, alkali, etc. and can be used for thermal imaging and infrared imaging in harsh environments. It can be used as a substrate for a variety of optical components, such as lenses, windows, etc. We provide germanium-based flat windows without coating or with AR coating, and we provide double-sided anti-reflective IR2 (8-12μm) AR-coated windows. Note: Special attention should be paid to the fact that germanium is a toxic material. Please wear gloves when using it and wash your hands after use.

We can customize Germanium (Ge) fluoride windows to meet your requirements according to your needs. If you have any questions or needs, you can contact us.
