4inch 6inch N-type germaniumGe VGF method substrates wafers ,customized Ge optical lens
Germanium (Ge) is the preferred lens and window material for high
performance infrared imaging systems in the 8–12 um wavelength
band. Its high refractive index makes Ge ideal for low power
imaging systems because of minimum surface curvature. Chromatic
aberration is small, often eliminating the need for correction.
Germanium is most widely used for lenses and windows in IR systems
operating in the 2 um - 12 um range. Its transmission is very
temperature sensitive, becoming opaque near 100°C. Environment does
not cause problems because Germanium is inert, mechanically rugged,
and fairly hard.
Germanium is a high index material that is used to manufacture
Attenuated Total reflection (ATR) prisms for spectroscopy. Its
refractive index is such that germanium makes an effective natural
50% beamsplitter without the need for coatings. It is also used
extensively as a substrate for production of optical filters.
Germanium covers the whole of the 8-14 micron thermal band and is
used in lens systems for thermal imaging. It can be AR coated with
diamond producing an extremely tough front optic.
Application as window, lens, beamsplitter, ATR prism or filter in
spectrometers and in thermal imaging.
we can provide 6 inch VGF method "zero dislocation" solar cell with germanium substrate enterprise. Products are widely used in space satellite solar cells at high power, high altitude reconnaissance uav, the ground concentrated solar power plant (CPV average photoelectric conversion efficiency is double times of the silicon solar power station, ultra-high brightness LED substrate used car. The factory has successfully developed an 8-inch solar germanium substrate with an international leading level, which will lay the foundation for future market expansion.
