LITTLE KNOWN FACTS ABOUT OPTICAL GERMANIUM LENSES.

Our aspheric lenses have a far more advanced front. The curvature progressively variations as you move from the center on the lens out to the edge. Our aspheric Ge lenses are most often accustomed to reduce spherical aberration in an optical system.Our spherical plano-concave germanium lenses are primarily accustomed to diverge a beam from the coll
