Summary

From the paper "What Is Fresnel Lens" it is clear that the Fresnel Lens is a thin plastic lens that is flat on one side and has ridges on the other; it is thick in the middle and reduces in different zones gradually tapers to the edges. The lens was created by Augustin Jean Fresnel…

Extract of sample "What Is Fresnel Lens"

Fresnel lens is disadvantaged in that its images are not as clear as those of conventional magnifying glasses and they are had to mount (Leutz & Akio, 56).

Fresnel lenses have varied applications, but they are majorly used as sunlight concentrators for multiple uses such as:

High-concentrated photovoltaic (HCPV); enables the concentration of sunlight to intensities of 300 suns or more by the use of Fresnel dish reflectors. This can be aided by either a linear Fresnel reflector dish or a refractive circular lens array.
Solar cookers: this is a device that uses concentrated sunlight as its only energy source for cooking. This cooker is very environment friendly.
Stirling Engine: This is a heat engine that works by alternating compression and expansion of air. It uses a Fresnel lens to concentrate light as a heat source for heating the working fluid.

Solar lighting systems; it is used for providing interior illumination using the light concentrated by Fresnel lens and optic fibers to supplement electricity, which makes it possible to use approximately 72-80% of the received sunlight. Read More
