fresnel lens
A Fresnel lens is a type of compact lens originally developed for use in lighthouses. It is made up of a series of concentric rings that are each a separate segment of a larger lens, allowing for a large aperture and short focal length while significantly reducing the amount of material required when compared to a conventional lens. This design gives the lens a distinct, ridged appearance. Today, Fresnel lenses are used in a variety of applications, including overhead projectors, rear-projection televisions, virtual reality headsets, and assistive reading devices.

Fresnel lens
A Fresnel lens is a type of compact lens originally developed by French physicist Augustin-Jean Fresnel for lighthouses. The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. A Fresnel lens can capture more oblique light from a light source, thus allowing the light from a lighthouse equipped with one to be visible over greater distances.
