Fresnel lenses are lenses resembling a planoconvex or planoconcave lens that is cut into narrow rings and flattened. If the steps are narrow, the surface of each step is generally made conical and not spherical. Fresnel lenses can be large glass structures as in lighthouses, floodlights or traffic signals, or thin molded plastic plates with fine steps; often used for field lenses.
