Paper Abstract

Commercial adoption of non-imaging optics has been limited in part by high length-to-aperture ratios of classical designs. Previous low-aspect-ratio designs have been limited to particular angular ranges. We will present designs with length-to-aperture ratios of 0.6 or lower, with nearly ideal etendue-preserving performance and efficiency over a wide range of collection and output angles. The results described will include raytrace simulations, experimental results, and demonstration units.
