A REVIEW OF OPTICAL GERMANIUM LENSES

Plano-convex Ge lenses are flat on just one aspect and convex on the other. These lenses Have a very beneficial focal size, and will often be useful for light-weight collimation.Normal resistance for EMI quality Germanium is about 4 Ohm x cm but it surely will depend on required standard of spurious sign suppression. Applying Ge window with such re
