Lenses have the functions of converging, diverging, and shaping beams in the optical path. Planar convex lenses (PCX)/biconvex lenses (DCX) converge the light rays; PCV/DCV lenses diverge light rays. Optical Glass Lenses are optical components that are transparent to certain light spectrums, and oriented for either collecting or diverging light. The functions of optical lensesencompass laser processing, image magnification, fiber collimation, etc. and the applications of Optical Glass Lensesare extensive, ranging from life science, and medical diagnoses, to defense and industrial production.
