Description
wide IR transmission range covering 1.8-16 µm opaque in visible range Germanium (Ge) based optical components are widely used for IR applications. Germanium (Ge) is well suited for manufacturing of windows and lenses for IR applications in lasers and optical systems. Ge components are used with AR coatings because of high surface reflectivity of substrate. The high refractive index ensures an exceptional single wavelength performance for a best "best form" singlet constructed from germanium.
