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.
