Abstract

The invention discloses a five-freedom-degree precise position fixing device for adjustment of lens sets, relating to a position fixing device for adjustment of lens sets, which solves the problem that the traditional optical adjustment method is more in accidental error and poor in consistency of an optical shaft of an adjusted optical product. The position fixing device comprises a supporting base, horizontal screw motors, horizontal position sensors, locating and fixing rings and positioning adjustment bolts; the first horizontal position sensor is arranged on the first horizontal screw motor; the first horizontal screw motor is connected with an X shaft at the bottom of the supporting base; the second horizontal position sensor is arranged on the second horizontal screw motor; the second horizontal screw motor is connected with a Z shaft at the bottom of the supporting base; the first locating and fixing ring and the second locating and fixing ring are fixed at two ends of the supporting base along the Z shaft; the front end of the positioning adjustment bolt is provided with a spring, the rear end of the positioning adjustment bolt is provided with a fixing bolt, the bolt is spun on the locating and fixing ring along a radial direction, and the front end of the bolt penetrates through the fixing ring. The five-freedom-degree precise position fixing device for adjustment of the lens sets is used for the precise positioning in adjustment of the lens sets.

Description

technical field [0001] The invention relates to a positioning and fixing device for lens group adjustment, which belongs to the technical field of optical adjustment. Background technique [0002] Optical assembly process technology has a direct impact on the performance of optical systems. With the increasing optical parameters and indicators of the optical system, the coaxial imaging optical system must achieve the imaging quality close to the diffraction limit. In the optical adjustment technology, the high-precision optical axis alignment technology has become a necessary means. [0003] The traditional optical adjustment method is to directly assemble the entire optical system, then qualitatively inspect the imaging quality of the optical system, and then determine the multi-dimensional adjustment direction and adjustment amount of the relevant components in the system according to the aberration characteristics and engineering experience. After the amount is adjusted,...
