Trade Lead Description:
Germanium Windows and Germanium lenses
Germanium (Ge) is the preferred lens and window material for high performance infrared imaging systems in the 8–12 um wavelength band. Its high refractive index makes Ge ideal for low power imaging systems because of minimum surface curvature. Chromatic aberration is small, often eliminating the need for correction.
Germanium is most widely used for lenses and windows in IR systems operating in the 2 um - 12 um range. Its transmission is very temperature sensitive, becoming opaque near 100°C.
