Applications

Optical materials, optics, laser, optical fibers, ceramics, glass, Li-ion battery, catalyst.

The refractive index (1.65) and optical dispersion properties of germanium dioxide (GeO₂) makes it useful as an optical material for wide-angle lenses, in optical microscope objective lenses, and for the core of fiber-optic lines. GeO₂ is transparent to the infrared spectrum. GeO₂ can be manufactured into IR windows and lenses, used for night-vision technology in the military, luxury vehicles, and Thermographic cameras.
