Abstrakt: In the paper, the approaches to the Fresnel lens design in a rectilinear (“classical”) and a curvilinear (“aspherical”) refracting profile versions are discussed regarding silicone-on-glass and 3D printing technology. The advantages of short-focus lenses with an increased Fresnel profile pitch are shown. The mathematical model used for concentrating solar radiation based on direct tracking of rays has made it possible to solve the problems of designing the concentrators and comparing their characteristics with due account for limitations of the manufacturing methods used and the Fresnel lens shape errors arising from manufacturing. Optimized design parameters of Fresnel lenses based on silicone (Wacker 604) and thermoplastic (Luxexcel Opticlear) materials are presented. [ABSTRACT FROM AUTHOR]
