Abstract
An improved optical focusing system is provided which includes a parabolic reflector and a fresnel lens situated with respect to one another to share a common focus point. The improved system is designed to collimate substantially all of the available light emitted from a light source located at the common focus point and project the light along a projecting axis. Depending on the limitations placed upon the size of the parabolic reflector, a retroreflector situated about the periphery of the fresnel lens can be added to the system to maximize the amount of emitted light which the system can process and collimate.
