Abstract
An optical device for frequency-selectively distributing light characterized by waveguides for directing a beam of light at a beam divider filter layer which will reflect light of one frequency and pass light of another frequency to form two partial beams and at least one color filter arranged in the path of one of the partial beams to filter out light of a frequency different than the main frequency of the beam. The optical device can be expediently provided by producing two components which support the optical waveguides and are provided with abutting surfaces, assembling the components with the beam divider layer disposed between the abutting surfaces and providing at least one color filter on a transparent body aligned with the beam divider layer. Preferably, the transparent body is a gradient lens and the two components are formed by cutting a single member, which is either a flat plate or a capillary, into the two components after a waveguide such as an optical fiber has been secured to the member.
