Germanium Window (Ge) is a chemically inert material with a transmission spectrum range of 2-12 μm. Stanford Optics has rich experience in manufacturing and supplying high-quality Optical Products.
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.
The Germanium Window is extensively utilized in:
At Stanford Optics, we prioritize the integrity and quality of our Germanium Windows (Ge). Each window is meticulously packaged to prevent contamination and damage during storage and transportation. Our stringent handling procedures ensure that the windows arrive in pristine condition, ready for seamless integration into your optical systems.
