Abstract
To provide an optical system that lengthens the lifetime of a fiber, an optical systemguides light beams emitted from a plurality of light emitting parts ep into a single optical fiber, the plurality of light emitting parts ep are arranged to be aligned along a first direction d, and the optical systemallows the light beams emitted from the plurality of light emitting parts ep to have different light collection centers which are offset from each other at least in a second direction d
