Plano-Convex Spherical Lens is widely use in optical display systems, projection optics systems, imagining optical systems, and laser measurement systems. It is best use where conjugate() point-- object distance, S or image distance S' is more than five times of the other. This lens is almost the most super form for both collimating() a point source and focusing collimated light;
