Fused Silica Plano-Convex Lenses
 

These lenses focus parallel beams to a light spot. This spot is a real image that can be projected on a screen or manipulated with a space filter like a diaphragm. The asymmetry of a plano-convex lens minimizes spherical aberrations when either the object distance or the image distance is more than 5 times the other. To minimize aberrations a plano-convex lens should be placed with the plane side pointing to the closest conjugate point - an object or an image whatever is closer.
