Abstract
The maximum concentration ratio has been derived by Winston for optical systems having an angular acceptance described by a step function. In this paper a more comprehensive relation between maximum concentration ratio and angular acceptance is obtained. This relation is valid for any acceptance function; the proof is based on thermodynamics and is valid for large angles as well. The total energies collected yearly by concentrators having different acceptance functions are compared. © 1979.File in questo prodotto:
