<P>PROBLEM TO BE SOLVED: To provide an optical multiplexing device which can use, without wasting as much as possible, light emitted from a plurality of light sources. <P>SOLUTION: An optical multiplexing device comprises: a plurality of light sources; a plurality of optical fibers which respectively propagate light emitted from the plurality of light sources; a plurality of rod lenses which are connected to respective emission ends of the plurality of optical fibers, and the length of which in the optical axis direction is m/4 of a meandering cycle of internal propagation light ("m" is an odd number equal to or greater than 1); and a condenser lens which is connected to the plurality of rod lenses. <P>COPYRIGHT: (C)2012,JPO&INPIT |
