Product Description
Germanium infrared lens, Germanium (Ge) widnow
Germanium has a high refractive index making it essential to add anti-reflection coatings to improve its transmission. It is inert, mechanically rugged and fairly hard making it suitable for external Infrared applications with durable AR coatings. Widely used in Infrared systems and as substrates for optical bandpass filters in the region from 2-14 microns. Available as generated lens blanks, polished windows, lenses and prisms with AR coatings, including Hard Carbon coating. The transmission of Germanium is very sensitive to temperature and above 70°C becomes opaque.
The coating: Anti-Reflection Coatings ,AR Coating @ 10.6μm;BBAR Coating @ 8-12μm; AR/DLC coating
