The advantage of using a Fresnel lens is its compact size compared with a conventional lens. Common usage includes overhead projectors, pocket-size magnifiers and motion detectors. The word \"Fresnel\" comes from the person who first used this design to construct lighthouse lenses, Augustin-Jean Fresnel, in 1820. The idea of dividing ...

LFQ0840 - Fresnel lens PMMA acrylic type
Compare
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 ...
