Fresnel lens Sketch :

It is a type of lens originally developed by French physicist Augustin-Jean Fresnel for lighthouses.The design of Fresnel lens enables the construction of lenses of large aperture and short focal length without the weight and volume of material that would be required in conventional lens design. Compared to conventional bulky lenses, the Fresnel lens is much thinner, larger, and flatter, capturing more oblique light from a light source.

Details:Compared to conventional bulky lenses, the Fresnel lens reduces the amount of material required compared to a conventional spherical lens by breaking the lens into a set of concentric annular sections known as "Fresnel zones", which are theoretically limitless. In the first variations of the lens, each zone was actually a different prism.

Though a Fresnel lens might look like a single piece of glass, closer examination reveals that it is many small pieces. For each of these zones, the overall thickness of the lens is decreased, effectively chopping the continuous surface of a standard lens into a set of surfaces of the same curvature, with discontinuities in steps between them.

In fact this product can be regarded as an array of prisms positioned in a circular fashion, with steeper prisms on the edges and a near flat convex center. Fresnel lenses are usually made of glass or plastic; their size varies from small to large. Since plastic lenses can be made larger than glass lenses, as well as being much cheaper and lighter, they are used to concentrate sunlight in multiple uses.

Material:3.3 borosilicate glass,a kind of optical glass.It has resistance to high temperature and high pressure.borosilicate also has good chemical stability.
