Abstract
In this paper, wide angular band Bragg holoconcentrators are considered. These complex holographic structures (transmission or reflection) are of the type of holographic sandwich which consist of a set of sub-holograms. Each sub-hologram is angular narrow-band concentrator, with quasi-rectangular angular diffraction efficiency characteristics, having concentration which is free of aberrations. Therefore, due to selectivity of Bragg effect, the global system reaches paraxial limit of the concentration ratio, even for wide angular spectrum of quasi-monochromatic illumination.
