摘要：

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　multi-plane　fitting　and　multi-focal　combinatorial　optimization　were　employed.　A　design　case　was　given　as　well　as　its　optical　simulation.　Results　show　that,　after　optimization,　the　Finel　lens　concentrator　efficiency　up　to　93%,　the　focused　beam　energy　uniformity　4.9,　meet　the　design　requirements.
