The collimating lens fixing tube and the semiconductor laser fixing tube are respectively fixed to the collimating lens fixing tube and the semiconductor laser fixing tube which are slidable relative to each other, and fixing means is provided for fixing the collimating lens fixing tube and the semiconductor laser fixing tube on the emission side of the collimating lens. Features: Semiconductor laser collimating device. (2) In paragraph 1 of the claims for utility model registration,
The material of the collimating lens fixing tube and the semiconductor laser fixing tube, the length from the fixing means to the collimating lens fixing reference position of the collimating lens fixing tube, and the distance from the fixing means to the semiconductor laser fixing fixing position of the semiconductor laser fixing tube. The length of a semiconductor laser collimating device is determined so that the focal position of the collimating lens and the light emitting point position of the semiconductor laser maintain a substantially constant positional relationship even when subjected to temperature changes.
