Abstract
Abstract The inventive system, which is used in transmitting illumination from a central source to a variety of remote locations, efficiently couples the light originating from an arc lamp, or similar source, into a multiplicity of flexible macroscopic fibers. The combination of the several elements of the inventive system results in a very efficient transfer of the energy of the light source to the fibers. Light from the arc lamp is fed into a circular light pipe, and then directly into a multi-sectored lens, without any requirement of a collimated lens. The multi-sectored lens then focusses the light into the multiplicity of flexible macroscopic fibers.
