- Fresnel lens - Wikipedia
A Fresnel lens ( ˈfreɪnɛl, - nəl FRAY-nel, -nəl; ˈfrɛnɛl, - əl FREN-el, -əl; or freɪˈnɛl fray-NEL[1]) is a type of composite compact lens which reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections

Augustin-Jean Fresnel was a French physicist who pioneered in optics and did much to establish the wave theory of light advanced by English physicist Thomas Young
- Fresnel Lens - U. S. National Park Service
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

- Advantages of Fresnel Lenses - Edmund Optics
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
- Fresnel Lenses | MEETOPTICS Academy
Fresnel lenses are a type of compact lens, made up of a series of concentric rings, each having a portion of the lens's curvature This unique design allows the lens to be much thinner, lighter, and less bulky than a traditional convex lens while still being able to focus light effectively
