摘要: A reflective optical illumination collector is described. In one example, the collector has a ring to collect light from a light source within a range of incident angles and to reflect the light off an inner surface of the ring to a target image of the collector. A plurality of rings concentric to the first ring may also be used. Each ring collects light from the light source within a range of incident angles and reflects the light off an inner surface of the respective ring to the target image of the collector.
