THE OPTICAL GERMANIUM LENS DIARIES

Plano-convex Ge lenses are flat on one particular aspect and convex on the other. These lenses Possess a positive focal length, and are sometimes useful for gentle collimation.Our spherical plano-concave germanium lenses are mainly accustomed to diverge a beam from a collimated gentle supply, or to boost the focal size of an optical technique.5µm.
