we can offers both electronics grade and IR grade Ge wafer , please
contact us for more Ge product information.
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.
