Abstract
Provided are a light source, a light source unit, and a light source module that have small sizes, high output, and high coupling efficiency with an optical system, and further, can efficiently dissipate heat generation sources to exhaust heat. In the light source unit of the present disclosure, the light source is a semiconductor laser array. This configuration can realize high output of the light source, and high output of the whole light source unit. The light source unit includes a lens that converts outgoing beams to parallel beams, and an optical element having a plurality of optical surfaces with different minute inclination angles with respect to a principal surface. The minute inclination angles of the plurality of optical surfaces that intersect with optical rays of the plurality of outgoing beams passing through a principal point of the lens are opposite to one another with respect to the principal surface.
