Abstract: To solve the problem that the traditional spherical Fresnel lens mold processing was difficult, low precision and high cost, a Fresnel lens design was presented to gain higher optical efficiency. In this design, spherical surface for center lens and inclined plane for outer rings based on the result of multiplane fitting and multi-focal combinatorial optimization were employed. A design case was given as well as its optical simulation.Resultsshow that, after optimization, the Finel lens concentrator efficiency up to 93%, the focused beam energy uniformity 4. 9, meet the design requirements.
