Down below you can find listing of major Qualities of Germanium along with its transmission and absorption spectra.
The sharp transmission Minimize-off before 2µm also enables germanium for use as a long go filter, only transmitting wavelengths in excess of twoµm and fully blocking almost everything ahead of it.
Materials Range: Higher-high quality germanium substrate is essential for developing substantial-general performance lenses, as any defects or impurities while in the germanium crystals could influence the optical Houses of the finished lens. Depend on Lattice to deliver high-quality tailor made-grown germanium to guarantee substantial-good quality lenses.
Germanium (Ge) can be a shiny, tricky component with a Knoop Hardness of 780kg/mm2 which makes it, together with its much more robust sister sapphire, the default candidate for programs the place the setting is likely To place a beating on the fabric.
