,LED Photometric Fresnel Lens
A Fresnel lens consists of a succession of concentric rings, each forming an element of a simple lens assembled on a flat surface to provide a short focal length. This lens is particularly used in lighthouses and searchlights to concentrate light into a relatively narrow beam.
Fresnel lenses consist of a series of concentric grooves etched into plastic. Their thin, lightweight construction, availability in small and large sizes, and excellent light gathering ability make them useful in various applications. Fresnel lenses are most often used in light gathering applications such as condenser systems or emitter/detector setups, and can also serve as magnifiers or projection lenses in illumination systems and image formulation.
A Fresnel (pronounced fray-NEL) lens replaces the curved surface of a conventional optical lens with concentric grooves. These contours act as individual refracting surfaces, bending parallel light rays to a common focal length. As a result, a Fresnel lens, while physically narrow in profile, can focus light similar to a conventional optical lens but offers several advantages over its thicker counterpart.
