Abstract
A photoirradiation device in which an optical system can be miniaturized and utilization efficiency of light can be improved in a manner that includes a first lens and a second lens, which share refraction of light to convert light beams emitted from a plurality of light sources into the light beams substantially parallel to an optical axis, and a third lens focusing the light beams from the second lens on an incident surfaceA of a lightguide. A fiber rod which can output uniform light beams in a manner that includes a first rod having a single fiber and a second rod having a plurality of fibers.
