title: Optical acceptance function of modified compound parabolic concentrators with linear corrugated reflectors.
abstract: For reflective cylindrical concentrators the acceptance function, as determined in the meridian plane, remains constant for more oblique planes of incidence. However, if the reflective surface has a linear corrugated structure, it is possible to increase the acceptance in the meridian plane at the expense of reduced acceptance at a more oblique incidence. A ray-tracing study has been performed on the optical properties of troughlike compound parabolic concentrators (CPC's) with linear corrugated reflectors. Calculations of angular acceptance for a modified CPC with concentration C = x is presented. A possible application of this new concentrator is as a secondary concentrator for tracking parabolic troughs.
