Germanium Window (Ge) Description

Germanium Window (Ge) is a chemically inert material with a transmission spectrum range of 2-12 μm. It is a commonly used infrared optical material with high hardness, good thermal conductivity, and insolubility in water. It is applied to infrared imaging systems and infrared spectrometer systems.

Window is one of the basic optical components in optics. It is usually used as a protective window for electronic sensors or detectors of the external environment. It is used to separate the environment on both sides, such as separating the inside and outside of the instrument, to isolate the inside and outside of the instrument from each other, thereby protecting the internal components. Windows do not change the system's magnification.
