Description
Germanium Focus Lens can be used in radiation detectors and thermoelectric materials.
High purity germanium single crystal has a high refraction coefficient, transparent to infrared light, does not transmit visible light and ultraviolet light, can be used as germanium windows, prisms or lenses specializing in infrared light.
Germanium’s ability to absorb light with the rise in temperature and continue to strengthen, 100 degrees Celsius or more on the transmittance of the obvious impact, seriously affecting the performance of the optical system. Germanium elements are usually coated with a reflection-reducing film due to their high surface reflectivity.
Main Highlights:
1).Good infrared spectrum characteristics
2).Excellent physical properties,
3).The base material has the functions of long pass, short pass, band pass, antireflection and reflection
4).Wide application
