An optical fiber apparatus is disclosed for providing light to optical and other instruments from an auxilliary light source which may include a laser. A disclosed embodiment comprises a retinascope with a light source optically connected to a fiber optic bundle having its individual fibers aligned in the shape of a circle at its input end and in the shape of a rectangle at its output end. Ferrules hold and align the fibers at both ends. The light source may be a pulsed or continuous wave laser producing substantially monochromatic light, or any other suitable poly- or monochromatic light source. The retinascope includes a holder for supporting the output ferrule and the fiber bundle output.
