EXAMINE THIS REPORT ON OPTICAL GERMANIUM LENSES

Plano-convex Ge lenses are flat on a person facet and convex on another. These lenses have a favourable focal duration, and will often be useful for light collimation.Usual resistance for EMI quality Germanium is about four Ohm x cm however it will depend on demanded volume of spurious signal suppression. Working with Ge window with these resistanc
