What Is Fresnel Lens - Lab Report Example

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:

1. 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.
2. Solar cookers: this is a device that uses concentrated sunlight as its only energy source for cooking. This cooker is very environment friendly.
3. 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.
