Our spherical plano-concave germanium lenses are mainly accustomed to diverge a beam from a collimated gentle resource, or to increase the focal length of an optical technique.
It's got exceptional Houses of transmission and Index of Refraction within the infrared spectrum which fits it for infrared optics. Despite the fact that our eyes are not able to see as a result of Germanium, infrared radiation (Specially 8-fourteen um) is incredibly transmissive by means of it.

Our metallic or dielectric coatings on mirrors are optimized to satisfy your necessities. Concurrently, these coatings shield the components against environmental influence and improve the reflection. Jenoptik checks all factors in accordance with DIN ISO or MIL requirements.

It could be cut, polished and shaped into lenses and Home windows used in infrared detector devices along with infrared spectroscopes.
Germanium is often a large index material that may be accustomed to manufacture Attenuated Full Reflection (ATR) prisms for spectroscopy. Its refractive index is these that Germanium helps make an effective pure 50% beamsplitter without the have to have for coatings.
Making a single crystal of germanium is the start line for production higher-quality elements. The crystal construction and defect density can noticeably impact its optical and electrical Homes.
Now for many entertaining stuff. We hear from a good amount of our buyers the place their germanium windows more info are viewing action. Here are some highlights:
Germanium was very first utilised on a large scale to replace Just about the most primary Digital parts, the diode.
