Lens supporting frame

Abstract

The invention discloses a lens supporting frame which comprises a lens supporting frame body. Multiple bolt mounting holes are formed in the lens supporting frame body, bolts penetrate the bolt mounting holes to be screwed into a laser device to connect the lens supporting frame body with the laser device, a supporting sleeve is arranged on each bolt in a sleeved manner, the upper end faces of the supporting sleeves are in abutted connection with the lower end face of the lens supporting frame body, and an elastic supporting member for contacting with the laser device is arranged on the lower end face of each supporting sleeve. When the laser device is debugged, an external force needs to be applied to the bolts, fine adjustment on direction and pitch angle of the lens supporting frame can be realized by adjusting pre-tightening force of the bolts, and the laser device is ensured to be capable of working normally, so that assembling and debugging time of the solid laser device is shortened, working efficiency is improved, universality of the lens supporting frame can be improved, and requirements on processing accuracy of the lens supporting frame can be lowered.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a lens support frame. Background technique [0002] Due to its small size, light weight, and flexible installation, small lasers have been widely used in many fields such as industry, medical treatment, military affairs, and scientific research. In the application process of lasers, optical lenses such as resonator mirrors and beam shaping mirrors in lasers need Supported by the lens support frame, due to machining errors in mechanical parts such as the laser chassis, lens support frame and crystal support frame, and assembly errors in the laser assembly process, in practical applications, errors may cause laser optical axis misalignment, The output efficiency is reduced, and when the error is too large, the laser may not work properly. Therefore, the laser requires very high processing accuracy for its chassis, lens support frame and other mechanical parts. [0003] At present, ...

[0002] Due to its small size, light weight, and flexible installation, small lasers have been widely used in many fields such as industry, medical treatment, military affairs, and scientific research. In the application process of lasers, optical lenses such as resonant cavity mirrors and beam shaping mirrors in lasers need Supported by the lens support frame, due to machining errors in mechanical parts such as the laser chassis, lens support frame and crystal support frame, and assembly errors in the laser assembly process, in practical applications, errors may cause laser optical axis misalignment, The output efficiency is reduced, and when the error is too large, the laser may not work normally. Therefore, the laser requires very high processing accuracy for its chassis, lens support frame and other mechanical parts.

[0003] At present, the existing method of adjusting the error is to adjust the angle of the optical lens by grinding the contact surface between the lens support frame and the laser installation surface to reduce the error, but this method takes a long time and the grinding The lens support frame is reduced in size and can only be assembled in a fixed laser, and the general use of the lens support frame is limited
