Abstract

Uniformity is a critical performance issue in illumination design. When Etendue is considered, the two main options to achieve uniformity are mixing rods and lens arrays. Mixing rods are quite effective, but they often require a large package size and usually only provide spatial mixing. A Turn-Mixer concept based on a turn prism with embedded partial mirrors has been explored as a means to provide both spatial and angular mixing. We show how this concept can be applied to mixing rod geometries.
