Enhanced visualization illumination system

Abstract

A first light source producing a first light beam with a first intensity and a second light source producing a second light beam with a second intensity. A light filter device receives the first light beam and transmits a filtered portion of the first light beam. A first angling device reflects the filtered portion of the first light beam in a first angled direction and a second angling device reflects the second light beam in a second angled direction. A mirror receives and in turn reflects the filtered portion of the first light beam reflected by the first angling device and the second light beam reflected by the second angling device to form a converged light beam with a third intensity.
