THE OPTICAL GERMANIUM LENS DIARIES

Plano-convex Ge lenses are flat on just one aspect and convex on one other. These lenses Have a very good focal duration, and are frequently useful for light collimation.Normal resistance for EMI quality Germanium is about 4 Ohm x cm but it surely is determined by required amount of spurious sign suppression. Using Ge window with this kind of resis
