Ge Window

Germanium (Ge) is in the range of 2-12 μm. Germanium is the most commonly used
for making optical lenses and optical windows in high-efficiency infrared
imaging systems. Due to the wide transmission range and opacity of visible
light, Germanium is very suitable for infrared lasers and optical systems for
the manufacture of optical components. Germanium's high refractive index and
minimal surface curvature make it an ideal material for making low-power
imaging systems.
