Dual Lens Optical Design.
The small circular grooves on the surface are shaped like the curved sections of a normal magnifying glass. These sections bend the light in the same way as a normal lens without needing as much material! Fresnel Lens. A Fresnel lens based on two-stage sunlight concentrator system was developed for TPV systems, consisting of a 0.36m2 Fresnel lens together with a secondary quartz concave–convex lens which gives a total concentration ratio of 4600 suns.

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
A very small amount of light is lost by absorption due to the thin geometry of the Fresnel lens. Fresnel Lens Magnifier Magnifiers are an example of one of the simplest applications of the Fresnel lens. Typi-cally, a magnifier is a positive lens that forms a virtual upright image.
