Germanium Wedge Windows

Germanium wedge windows are a commonly used infrared optical material with high hardness, good thermal conductivity, and insoluble in water. Usually used as a protective window for electronic sensors or external environmental detectors, and to change the deflection path of light. The design with wedge-shaped shape, high transparency, high anti reflection, high thermal stability, etc., is applied in infrared imaging systems and infrared spectrometer systems. It can be coated with reflective film, anti reflective film, filter film, spectroscopic film, polarizing film, and metallization film systems.
