Dome Infrared Fresnel Lens Led Module 80mm Aacrylic pc Big Underwater Camera Lens For PIR Motion Module Fresnel lenses consist of a flat surface with interspaced, concentric steps whereby each step corresponds to the surface of a conventional lens. Each step thereby acts as a refractive surface, much like a prism. This gives the Fresnel lens a common focal length equivalent to a traditional lens, but with a fraction of the thickness. Additionally, because the lens is so thin

Custom Fresnel Lens For LED Photometric Or LED Flashlight Fresnel Lens Introduction 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 Lens Parameters Fresnel lenses consist of a series of concentric grooves etched into plastic. Their thin,
