A SIMPLE KEY FOR OPTICAL GERMANIUM LENS UNVEILED

Plano-convex Ge lenses are flat on just one aspect and convex on another. These lenses Use a optimistic focal duration, and will often be useful for mild collimation.Our spherical plano-concave germanium lenses are mostly accustomed to diverge a beam from the collimated light-weight resource, or to increase the focal length of an optical process.Va
