Abstract

A light source apparatus includes a first light source that includes a plurality of first light emitters arranged in a row along a first direction and emits a first luminous flux, a second light source that includes a plurality of second light emitters arranged in a row along a second direction and emits a second luminous flux in a direction in which the first luminous flux is emitted, and a combiner that combines the first and second luminous fluxes with each other to produce combined light and outputs the combined light to an irradiated region. The combined light has a combined light intensity distribution in which a first region where a light intensity of the first luminous flux is maximized and a second region where a light intensity of the second luminous flux is maximized do not overlap with each other.
