(Problems to be Solved by the Invention) As mentioned above, the collimator lens used in combination with a semiconductor laser generally has a focal length of 5 to 8 InIR.
Because of its short length, its positioning must be performed with high precision. However, in order to adjust the position of the conventional lens barrel to the lens barrel holding means, screw grooves are formed on both the lens barrel and the lens barrel holding means, and the lens barrel is rotated relative to the lens barrel holding means. Even if the lens barrel is rotated with high precision using an external jig, it is difficult to make the pitch of the thread grooves finer than a certain level, and the screw itself may have looseness. There is a problem in that it is not possible to achieve the desired accuracy due to certain things that may occur.

As is well known, since the semiconductor laser 4 emits diverging light, the laser beam emitted from the semiconductor laser 4 passes through the -H collimator lens 1 and is converted into parallel light, which is then used for various purposes. In order for the collimator lens 1 to accurately convert the incident laser beam into parallel light, the distance mi between the collimator lens 1 and the semiconductor laser 4 should be approximately equal to the focal length of the collimator lens, as indicated by the arrow a in the figure. Although directional positioning must be performed with high precision, the focal length of the collimator lens is short, 5 to 8M, so the positioning described above is extremely minute. Therefore, in this embodiment, the flange portion 2b of the lens barrel 2 is
A ferromagnetic plate 6 made of stainless steel or the like is attached to the front surface of the ferromagnetic plate 6, and a position adjustment jig 8 whose tip is formed by a magnet 7 is brought into contact with the ferromagnetic plate 6, and the ferromagnetic plate 6 and the magnet 7 are aligned. The lens barrel 2 is slid in the direction of the arrow using suction force to adjust its position. Hereinafter, a specific example of this position adjustment jig 8 will be explained with reference to FIG.

The position adjustment jig 8 moves the micrometer head 9 in the direction indicated by the arrow in FIG.
By moving the micrometer head 9 in the direction of arrow C, the pressing section 10 is moved in the direction of arrow C'. That is, the adjustment 1Jiljlj11 is provided with an L-shaped arm 11b, the bent part of which is rotatably supported by the support 11a, the tip of the micrometer head 9 is in contact with one end of the arm 11b, and the other end is is locked by a pin 11c to a movable plate 11d in which an elongated hole is formed and a pressure distribution part is fixed, so when the micrometer head 9 presses the arm 11b, the movable plate 11d is moved to the support by the arm 11b. The guide groove 118G formed in the guide groove 11a is slid along to move the pressing part 10. Note that the bent portion of the arm 11b is pivotally supported by a spring or the like so as to always urge the micrometer head 9 in the direction of arrow C, so that the micrometer head 9 can move either in the direction of the arrow or in the direction of arrow C. Even though
The micrometer head 9 never leaves the arm 11tl. Also, from the bending part of the arm 11b to the moving plate 11d
Since the distance from the side end is smaller than the length from the bent part to the end on the micrometer head side, the movement value of the micrometer head is smaller at the pressing part 10. It will be done. Therefore, with the position adjustment jig 8, extremely small lens barrel side means can be controlled.

As mentioned above, the lens barrel 2 attracted by the position adjustment jig 8, which moves extremely precisely, moves back and forth as the pressing part 10 of the position adjustment jig 8 moves back and forth, and the lens barrel 2 holds the lens 1 in the tube. Since the interior of the section 3 is oriented to the left, precise positional adjustments can be made freely so that the collimator lens 1 is placed at a predetermined position.

When the lens barrel 2 is placed in a predetermined position, the lens barrel 2
is fixed to the lens barrel holding means 3 by injecting adhesive. That is, the lens barrel holding member 3 has a first
As shown in the figure, an adhesive injection port 3a is formed, and the adhesive is injected from this injection port 3a and transmitted to the circumferential surface of the lens barrel. By injecting the adhesive in this manner, the lens barrel can be fixed at a precisely adjusted position. In addition, if the position to be fixed by the lens barrel can be specified in advance, forming a groove 2C on the circumferential surface of the lens barrel as shown in FIG. 3 will ensure that the adhesive is firmly attached to the lens barrel. It can be distributed throughout the tube. Also, when the adhesive hardens, the volume changes and the lens! If there is a possibility that the position of the lt cylinder 2 may shift, measure the position shift m due to the volume change in advance.
The lens barrel may be positioned in advance at a position looking into the misaligned peak.

As mentioned above, the lens barrel is slidably held by the lens barrel holding means, and a ferromagnetic plate is provided on a part of the lens barrel, so that the contact portion is formed by a magnet and the position is adjusted. The lens barrel can be freely slid and positioned using the jig. In addition, according to this method, when positioning is performed by engaging the lens barrel and the lens EM 1m holding member through threaded grooves, the positioning accuracy is limited by the pitch of the full thread, and the positioning accuracy is limited by the play in the threaded grooves. The disadvantage of reduced viscosity no longer occurs. Note that instead of attaching the ferromagnetic material to a part of the lens barrel, the entire lens tit R may be formed of the ferromagnetic material. Alternatively, a magnet may be fixed to the lens barrel side, and the position adjustment jig side may be made of a ferromagnetic material. Further, the position adjustment jig is not limited to the one shown in the above embodiment, but may have any structure as long as it can finely adjust the position of the lens barrel. For example, a magnet may be provided at the tip of the micrometer head to directly press the lens barrel.
