ABSTRACT:
The present invention relates to a concave mirror composed of a plurality of planar facets. According to the invention, all the facets are identical and the two dimensions of said facets are such that the square root of their product is at least approximately equal to the ratio of the focal distance of the mirror and of the square root of the rate of concentration of the mirror. The invention finds application in the concentration of solar energy in solar generators.
