Germanium for IR Optics
Ge is the preferred lens and window material for high performance
infrared imaging systems in the 8–12 µm 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
