Abstract

An apparatus for providing multiple collimated light beams from optical fibers and the method for producing such beams. The apparatus includes first and second optical fibers that carry light of first and second wavelengths, respectively, a fixture that maintains the fibers in a fixed relationship to one another, and a collimating lens. Light from each of the first and second optical fibers diverges from a face of the fixture. The collimating lens produces first and second collimated light beams that are displaced relative to one another from the light leaving the face. The face of the fixture is positioned to correct for chromatic aberration in the lens.
