1. A light source module comprising:
a substrate;
a first light source mounted on the substrate and configured to emit a first light beam having a first optical axis;
a second light source mounted on the substrate and configured to emit a second light beam parallel to the first light beam;
a beam combiner configured to combine and emit the first light beam and the second light beam;
an adjuster including a socket connected to the second light source and disposed between the substrate and the second light source, wherein the socket is a rotating body having a second optical axis of the second light beam as a center axis, the second light source being coaxially connected to the socket; and
a holder holding the first light source and the socket,
wherein the adjuster is configured to adjust a mounting height of at least one of the first light source or the second light source on the substrate to vary at least one of (a) a first optical path length of the first light beam, the first optical path length extending from the first light source to a position where the first light beam is combined with the second light beam by the beam combiner or (b) a second optical path length of the second light beam, the second optical path length extending from the second light source to the position where the first light beam is combined with the second light beam by the beam combiner.
