Plano-Convex lenses

Plano-Convex lens is a convergent lens with one plane surface and one convex surface. It’s mostly used where one conjugate point is more than five times the other, also where both conjugates are on the same side of lens.
Plano-convex lenses are used in many applications including telescopes, collimators, magnifiers, radiometers, condensers.
