An optical fiber is operably coupled to the handpiece, and the optical fiber is optically coupled to the optical cable to receive and transmit the light beam. An optical assembly, optically coupled to a distal end of the optical fiber, is provided for receiving the light beam and providing the light beam to illuminate an area, wherein the optical assembly comprises a nested compound parabolic concentrator ("CPC") cone. A cannula is operably coupled to the handpiece and optical assembly, for housing and directing the optical assembly to illuminate the area. 944541
