A SIMPLE KEY FOR OPTICAL GERMANIUM LENS UNVEILED

Plano-convex Ge lenses are flat on just one side and convex on the opposite. These lenses Possess a positive focal size, and are frequently useful for mild collimation.Our spherical plano-concave germanium lenses are mostly accustomed to diverge a beam from a collimated light-weight source, or to enhance the focal size of the optical method.Anythin
