Our germanium lenses Possess a significant refractive index—the highest refractive index among readily available IR transmitters. In addition it displays minimal chromatic aberration on account of very low dispersion.
5µm. This leaves germanium as the best and only choice for brutally tricky IR programs. This is usually why you will note germanium windows and lenses serving in spots as inhospitable as outer space, battlefields and in the middle of superior-powered CO2 laser techniques. Far more on this later on.
Germanium has outstanding thermal stability. It could withstand significant functioning temperatures without degrading optical functionality.
This permits optimal IR transmission important to night vision/thermal imaging. As these Home windows can have excellent sensitivity at very long assortment, This allows warfighters to retain prolonged stand-off distances increasing basic safety and mission-effectiveness. Germanium can be a literal life-saver.
Avantier Inc. is surely an unparalleled chief in furnishing imaging techniques options and optical remedies.
Shanghai Optics manufactures high-quality germanium lenses in An array of well-known measurements, from 5m m to 350 mm in diameter.

It can be cut, polished and formed into lenses and windows Employed in infrared detector products along with infrared spectroscopes.
Beneath you will discover list of most important Houses of Germanium and also its transmission and absorption spectra.
This higher-density window contains a thermal escape which makes the transmission minimize given that the temperature in the window raises.
They could be Employed in beam expanders, and will also be utilized to harmony out aberrations which ended up released by other lenses in an optical arrangement.
Be aware: Because of the current change within the Chinese exporting policy, the exporting of Germanium optics is restrained and less than strict supervision. Make sure you inquire us if you intend to order the Germanium Lenses
