OPTICAL GERMANIUM LENSES FUNDAMENTALS EXPLAINED

Plano-convex Ge lenses are flat on one particular facet and convex on one other. These lenses have a constructive focal size, and will often be employed for mild collimation.Our spherical plano-concave germanium lenses are mainly used to diverge a beam from a collimated gentle resource, or to increase the focal length of an optical program.Nearly a
