Description

The Germanium Window (Ge) is a premier infrared optical component known for its chemical inertness and expansive transmission spectrum ranging from 2 to 12 μm. Engineered from high-purity germanium, this window boasts superior hardness, excellent thermal conductivity, and complete insolubility in water, making it an ideal choice for demanding infrared applications.

As a fundamental element in optical systems, the Germanium Window serves as a protective barrier for electronic sensors and detectors, shielding them from external environmental factors. Its robust construction ensures the separation of internal components from the external environment without affecting the system's magnification, thereby maintaining optimal performance and longevity of your optical instruments.Germanium Window (Ge) Application

Germanium Window (Ge) is the most commonly used material for making optical lenses and optical windows inefficient infrared imaging systems.

Applications

The Germanium Window is extensively utilized in:

Packaging and Handling
