THE BEST SIDE OF OPTICAL GERMANIUM LENS

Plano-convex Ge lenses are flat on one particular facet and convex on one other. These lenses Possess a favourable focal size, and will often be useful for light collimation.Our spherical plano-concave germanium lenses are mainly accustomed to diverge a beam from the collimated light supply, or to improve the focal length of the optical method.Just
