Abstract

A refraction method and a compound lens is disclosed for concentrating solar beam in a non-imaging manner for its heat to be harvested and utilized, for example, for generating electricity with thermo-electric or thermocouple circuit when its hot junction is heated. Solar beam (S1), which may be collected over a wide span of the sun's movement without need for tracking, is first refracted with a first positive refractory element which may preferably be an asperical biconvex lens (11). The exiting, i.e. second solar beam (S2), at a still convergent angle is then refracted by a second negative refractory element which may preferably be a biconcave lens (12). The exiting, i.e. third solar beam (S3), converges upon a third positive refractory element, preferably another aspherical biconvex lens (13), which concentrates the exiting solar beam (S4) onto the predetermined heat collection surface area (120). The sum of all the curvature surfaces of the compound lens times the indices of refraction is about zero such that the field of focus is flat. Preferably, the sum of refractive powers of the first and third aspherical biconvex lenses is substantially counter-balanced by the refractive power of the second biconcave lens placed thereinbetween said first and third lenses.
