Multifunctional prism blunt wedge e.g. for solar radiation concentration, has defined divergence angle falling on wide aperture surface of PSK by total reflections at boundary surface between PSK flanks and ambient air

摘要

The wedge (PSK) has a defined divergence angle falling on a wide aperture surface of the PSK by total reflections at the boundary surface between the PSK flanks and the ambient air. Additional reflections are within the final range of the PSK on the smaller projected surface.
