Optical windows are falt, plane parallel plates which are often used as protective barriers for electronic sensors or detectors from outside environments. When selecting windows, please consider materials, transmission, scattering, parallelism and resisitance to certain environment or mechanical properties of the substrate.
Germanium window /Ge windowGermanium window /Ge window is widely used in infrared lenses, including military application and civil use. It is mainly used in airborne infrared lens, shipborne infrared lens, road-based infrared lens, car infrared lens, infrared gun aiming lens, helmet infrared len and handheld infrared lens, etc.; Civilian infrared ge window is mainly used in various surveillance cameras, night-assisted pilots, security, civilian vehicles, civilian vessels, civil aircraft, police and so on.
