5x0.5 mm Germanium Optical Window, DLC Coated

Product description

Germanium windows and lenses are essential for high-performance infrared imaging systems, particularly in the 8-14 μm and 1.7-3 μm wavelength bands. Their unique properties, including low chromatic aberration and high refractive index, make them ideal for thermal imaging applications. With customizable sizes and coatings such as DLC, AR, and HR, these components ensure optimal performance in demanding environments. Germanium’s mechanical ruggedness and inert nature further enhance its reliability in various applications, including spectrometry and ATR prisms.
