In the range of 2-12 μm, germanium is the most commonly used material for the production of spherical lenses and windows for high efficiency infrared in imaging system. Germanium has a high refractive index (about 4.0 through 2-14μm band), usually do not need to be modified due to its low chromatic aberration in low power imaging systems.
