Ge (Germanium) window

Ge windows are commonly used in various optical systems, including:

1. Infrared Spectroscopy: Ge windows are used in IR spectrometers and other optical systems that operate in the IR range due to their high transmission in these regions.

2. Laser Systems: They serve as protective windows for laser cavities and optical paths in laser devices, especially those operating in the IR spectrum.

3. Thermal Imaging: Ge windows are used in thermal imaging cameras and other IR detection systems.

4. Optical Communication: In fiber optic communication systems, Ge windows can be used for interfaces and other optical components that require IR transmission.

5. Aerospace and Defense: Ge windows are used in sensors, telescopes, and other optical instruments on board aircraft and satellites.
