The 5-Second Trick For optical germanium lenses
Plano-convex Ge lenses are flat on a single facet and convex on the opposite. These lenses Possess a optimistic focal duration, and in many cases are employed for light collimation.Our spherical plano-concave germanium lenses are primarily utilized to diverge a beam from a collimated light-weight source, or to increase the focal size of an optical
