plano-convex lens

A plano-convex lens is a transparent glass or plastic piece with one flat surface (plano) and one outward-curving surface (convex). This design helps focus or converge light rays that pass through it. When light enters the curved side, it bends toward a common point called the focal point, making the lens useful in devices like cameras, microscopes, and eyeglasses. The flat side helps in mounting or positioning the lens precisely. Overall, a plano-convex lens efficiently directs light, providing clear images or focus in optical systems.
