Abstract
A multiplexing optical system includes a light source, a lens and a lens array. The light source includes a plurality of light emitting elements of surface emitting lasers. The lens is configured to change and condense optical paths of laser light beams emitted from the light emitting elements. The lens array includes a plurality of lens regions arrayed so as to correspond to respective optical paths of the laser light beams changed by the lens, and is configured to condense the laser light beams by the lens regions to form a multiplexed beam.
