The Fresnel Lens

Fresnel Lens 40 Mile Point Lighthouse The fresnel lens reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections. an ideal fresnel lens would have an infinite number of sections. A fresnel lens is a flat, lightweight lens that uses a series of concentric grooves carved into its surface to bend light the same way a thick, curved glass lens would.

Fresnel Lens Glass Fresnel lens, succession of concentric rings, each consisting of an element of a simple lens, assembled in proper relationship on a flat surface to provide a short focal length. the fresnel lens is used particularly in lighthouses and searchlights to concentrate the light into a relatively narrow. In a fresnel lens, hundreds of pieces of specially cut glass surround a lamp bulb. this design intensifies the glow from the light, focusing rays of light that would normally scatter into a single, intense beam of light, which shines out in a specific direction. Fresnel lenses are a type of compact lens made up of concentric rings, each representing a section of a conventional lens, designed to focus light while using less material. In 1822 fresnel's hand ground concentric groove lenses, which were used extensively in lighthouses along the french coast, popularized the concept. subsequently, this type of lens came to be known as a fresnel lens.

In a traditional convex lens, the bulk of the material in the center merely transmits the light and does not contribute to the bending action. a fresnel lens capitalizes on this by dividing the optical surface into a set of concentric, annular sections, sometimes called zones. Fresnel lenses consist of a series of concentric grooves etched into plastic. their thin, lightweight construction, availability in small as well as large sizes, and excellent light gathering ability make them useful in a variety of applications. That's why lighthouses use hollow, lightweight fresnel lenses, which have a very distinctive "stepped" surface that bends the light as much as a thick, heavy glass lens. they're named for augustin jean fresnel, (1788–1827), the french physicist who pioneered them in the early 19th century. Fresnel lens — it might sound like a fancy term, but its concept is simple. imagine a conventional lens, thick in the middle and tapering to the edges, much like a lentil. now, what if you could flatten the lens surface without losing its magnifying power? enter the fresnel lens.
