Edmund Optics offers a variety of Fresnel lenses designed for visible and infrared applications. To maximize the performance of the lens, please use the grooved side of the Fresnel lens facing the longer conjugate point. For example, when using a Fresnel lens with a light detector, the grooved side of the lens should not face the light detector. Aspherical Fresnel lenses with aspherical profiles patterned in a Fresnel design improve focusing performance and spot size. Cylindrical Fresnel lenses focus light in only one axial direction.

basic information
Fresnel lenses are used in many focusing applications, such as condenser systems and emitter/detector configurations. A Fresnel lens is an optical lens that has a series of concentric grooves molded into a thin, flat plastic substrate. Each groove functions as a refractive surface, while the thin substrate minimizes light absorption. A higher spatial density of grooves improves image quality, but a lower density increases overall efficiency. Fresnel lenses are generally not used as magnifying glasses or projection lenses due to the occurrence of higher-order distortions.
