Practical concentrators attaining maximal concentration

Optics Letters, 1980
A new class of radiation concentrators is described that achieve maximal concentration of radiation from a uniform source. Unlike ideal concentrators, which accept all radiation within a given acceptance angle and none outside, the new maximal concentration collectors may reject some radiation from within the nominal acceptance angle.
