“…The aim of this design is to avoid the metalized surfaces, which cause reflection losses and are difficult to manufacture, and to optimize the position of the emitter/receiver for the encapsulation, electrical connection, and heat sink. A concentrator with a magnification of 1256 × has a theoretical efficiency of 100% (without optical losses) with an acceptance angle of ± 1.7° and aspect ratio of 0.34 [37,39]. Figure 10 shows another 3D freeform device designed by SMS for CPV applications.…”

“…Since 1990, Light Prescriptions Innovators Europe (LPI, Altadena, USA) has designed a variety of concentrators used in CPV, including R(refractive)R [37], X(reflective)R [37], RX [38], RXI [total internal reflection (TIR)] concentrator [38], TIR-R concentrator [37,39], and so on. Taking the TIR-R concentrator, for example, as shown in Figure 9, it has two parts: the primary surface is TIR surface as a microstructure with infinitesimal flat facets, and the secondary surface is refractive surface.…”

Freeform optics has certain characteristics such as complex surfaces and more degrees to be controlled, so that it is capable of achieving optical mapping relationship, which cannot be achieved by the conventional optical surfaces. There is no applicable method for designing all freeform optics in the optical field until now. The selection of design methods should be based on specific applications. The paper introduces the main optical freeform design methods and their typical applications.
