Ge Germanium Window
Germanium(Ge) is a widely used material for lenses and windows in thermal imaging and FLIR applications. It is also used extensively as a substrate for optical filters. The useful transmission range is from 2µm to15µm, making it good for far infrared. But Germanium has the property of thermal runaway, meaning the transmission decreases as temperature increases. As such, Ge window should be used at temperatures below 100. Germanium’s high density (5.22g/cm3) should be considered when designing for weight-sensitive systems.
Optical Window is one of the most commonly used optical elements, usually used as the optical view window of sensor, analyzer, or outdoor environment protection, vacuum sealed window etc. China Star Optics offers custom optical window. BK7 Window, Fused silica window, Sapphire window, CaF2 window, Zinc Selenide window, Germanium window, Silicon window etc. precision optical protective windows can be customized. Laser windows range from UV to VIS, NIR, SWIR further MWIR and LWIR are available.
