Germanium sputtering targets are made of 5N germanium crystals, due to its wide transmission range in the infrared and opaqueness in the visible light regions, germanium sputtering targets are used for depositing germanium thin film on the optic of thermal imaging camera. Such optics are usually working in the 8 to 14 micron range for passive thermal imaging and for hot-spot detection in military, mobile night vision, and fire fighting applications. It’s also used in infrared spectroscopes and other optical equipment that require extremely sensitive infrared detectors.
But as germanium thin film has a very high refractive index (4.0), so it must be coated with a anti-reflection film.
