A Fresnel lens is a lens that arranges the curvature of the lens in a flat plane.
While being flat, it is a lens, which saves space and weight, and allows for the creation of lenses with a focal length shorter than the diameter, something that cannot be achieved with spherical lenses. It is used in camera viewfinder lenses, overhead projector condenser lenses, rear projection screens, and in recent years for applications such as solar energy concentration, LED lighting lenses, and optical sensor lenses. Japan's special optical resin Fresnel lens products can manufacture various sizes and shapes of Fresnel lenses according to customer requests, in addition to standard specifications.
