Abstract

The light source device according to the present disclosure includes a light source, a light transmission part, a light intensity converter, and a collimator. The light source includes a plurality of semiconductor laser elements. The collimator includes a first lens array that has a plurality of collimator lenses. Each collimator lens collimates laser light emitted from a single semiconductor laser element. The light intensity converter includes a second lens array that has a plurality of lens arrays. Each lens array includes a plurality of lens cells so as to uniformize a light intensity distribution of the laser beam emitted from the single semiconductor laser element. The light intensity converter is disposed on a main surface of the light transmission part on the light source side. The collimator is disposed on a surface of the light transmission part opposite to the light source side.
