Method for manufacturing optical element

Abstract

The present invention provides an optical component processing method, and includes the following procedures: providing an optical lens needing to be processed and a light filtering piece needing to be processed, using an optical adhesive to bond a surface of the light filtering piece and a surface of the optical lens together; solidifying the above optical adhesive to bond the light filtering piece and the optical lens together; processing the bonded optical lens and the light filtering piece; removing the optical adhesive and then obtaining the processed optical lens and the processed light filtering piece which are separated. In the technical proposal, the processing precisions of the optical lens and the light filtering piece are essentially consistent, that can facilitate to improve the assembly precision, to reduce the production time, and to improve the yield.

Description

technical field [0001] The invention relates to a processing method for an optical element, in particular to a processing method for an optical element related to a lens module. Background technique [0002] The processing process of optical components usually includes material selection, cutting, rounding, forming, coarse and fine grinding, polishing and centering and edging. The cutting process refers to the process of cutting out the processing body of an appropriate size from the entire optical glass body after material selection. Rounding, also known as rounding, refers to the process of grinding the cut body into a circular shape with a grinding wheel. Forming refers to the process of forming a spherical or aspherical surface with a predetermined radius of curvature by grinding or molding the green body after rounding. The purpose of the rough grinding and polishing process is to further refine the surface of the formed optical element, such as eliminating knife line...

AI Technical Summary

Problems solved by technology

First of all, lenses and filters are produced separately, and different processing machines may cause inconsistencies in the processing accuracy and processing errors of lenses and filters, resulting in low assembly accuracy when assembling lens modules

Secondly, the centering and edging of the lens and the rounding of the filter need to be processed separately, that is, during the processing, the lens and the filter need to be put on the machine, fixed, processed, and removed from the machine, which increases the production cost. time, which is not conducive to increasing productivity and machine utilization
