Copper germanium selenide, 99.99% (metals basis), Thermo Scientific Chemicals
Description
The most notable physical characteristics of germania (GeO2) are its high index of refraction and its low optical dispersion. These make it especially useful for wide-angle camera lenses, microscopy, and for the core part of optical fibers. Germanium-on-insulator substrates are seen as a potential replacement for silicon on miniaturized chips.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
