Details:

Germanium (Ge) is a high refractive index material (4.0 @ 10 microns) with good long wavelength transmission in the infrared spectral region. At elevated temperatures the free carrier absorption becomes important and at 200 °C it is almost opaque. The high refractive index of Ge limits transmission in applications where an anti-reflective coating cannot be used.
