PROBLEM TO BE SOLVED: To provide a multiplexed laser light source in which a plurality of collimator lenses corresponding to a plurality of laser modules are fixed while suppressing dispersion in spring force.SOLUTION: A multiplexed laser light source comprises laser modules 40a, 40b, 40c, collimator lenses 20a, 20b, 20c, a base 30, a leaf spring 10 and a reinforcing plate 50. The laser modules 40a, 40b, 40c emit laser light beams. The collimator lenses 20a, 20b, 20c make the laser light beams into parallel light beams. The base 30 includes lens boxes 30a, 30b, 30c for fixing the collimator lenses 20a, 20b, 20c. The leaf spring 10 is provided on the base 30 and fixes the collimator lenses 20a, 20b, 20c by pressing them onto the base 30. The reinforcing plate 50 is provided on the leaf spring 10 and screwed together with the leaf spring 10 and reinforces the leaf spring 10 by pressing it onto the base 30. |
