| 主权项 | 1. An optical system configured to direct a light beam emitted from each of a plurality of light emitting parts arranged to be aligned along a first direction to a single optical fiber, comprising an optical element having an emission surface that is designed to be located closest to the optical fiber, wherein the emission surface includes a lens array including a plurality of lens elements that are arranged to be aligned along the first direction and that refract the light beam emitted from each of the plurality of light emitting parts into a different orientation in a second direction that is orthogonal to the first direction so that the respective light beams emitted from the plurality of light emitting parts have different light collection centers on the optical fiber which are offset from each other at least in the second direction. | ||
