PURPOSE:To prevent the deviation of an optical axis due to outside temperature change after fixing a semiconductor laser light source. CONSTITUTION:A semiconductor laser light source 1 is press-infected into a straight through-hole 11a of a holder 11 after a positioning by a jig which is not shown by a figure. The semiconductor laser light source 1 doesn't have a stress to the direction of the optical axis of a collimator lens 6, so that the generation of the deviation of the direction of the optical axis due to the stress relaxation can not be generated. |
