Process for designing a freeform Fresnel lens
Optical Engineering, 2010This paper describes a process for designing a faceted freeform Fresnel lens. Where a traditional Fresnel lens uses a profile revolved around a central axis, a freeform Fresnel lens uses individual triangular or trapezoidal facets that comprise a freeform surface. This type of lens combines the capability of a freeform surface with the benefits of a

Tracing finite rays through a Fresnel lens
Applied Optics, 1983In this study we show that with minor modifications it is possible to adapt an existing optical design program to trace finite rays through a system containing Fresnel surfaces. Practical examples are given to illustrate the validity of our rather simple approach to this problem.

Solar Geyser Using Spot Fresnel Lens
Journal of Fundamentals of Renewable Energy and Applications, 2016Fresnel lens based concentrating devices are not only gaining scope in the Photovoltaic industry, but also in solar thermal based industries. Fresnel lens is an optic device which concentrates the incoming light onto a spot or onto a line. This means that the temperature at that point will be significantly high.
