OPTICAL LENS ADJUSTING JIG FOR SEMICONDUCTOR LASER
Document Type and Number:
Japanese Patent JPH01178907
Kind Code:
A
Abstract:
PURPOSE:To make a rough and a fine adjustment by a simple structure by adjusting the position of an optical lens by using a 1st shaft which has an eccentric hole and a 2nd shaft which engages the eccentric hole rotatably. CONSTITUTION:The adjusting jig 8 provided with an eccentric pin 10a is inserted into a hole 3a bored in the side face of a base 3 to insert the eccentric pin 10a into the groove 4a of a cylinder 10a, and the adjusting jig 8 is rotated to move back and forth the cylinder 4, thereby adjusting a focus position F. Further, the cylinder part 9b of the 1st shaft 9 is inserted into the hole 3a of the base 3 to engage the eccentric pin 10a with the groove 4a of the cylinder 4, and the knob 9a of the 1st shaft 9 and the knob 11 of the 2nd shaft 11 are rotated at the same time to adjust the position of the lens 5 roughly within a range up to a 2Xl1 quantity. Then the knob 9a of the 1st shaft 9 is fixed and the knob 11 is rotated to make the fine adjustment within a range of a 2Xl2 range. Consequently, when the position of the optical lens is adjusted, the rough adjustment and fine adjustment are made by one-time setting.
