Problems solved by technology

However, the actual trial production found that the imaging quality of the optical lens and camera module often deteriorates compared with the imaging quality obtained in the active calibration stage. This degradation sometimes exceeds the tolerance range, resulting in defective products
The applicant's research found that after the active calibration process was introduced into the assembly of the optical lens or camera module, the variation of the glue material, lens barrel or lens, and other unknown factors may be the cause of the above problems

Abstract

The present application relates to an optical lens, comprising: a first lens barrel, a first lens having a first optical region and a first structural region, a second lens component and a first adhesive material. The second lens component comprises a second lens barrel and at least one second lens mounted on the second lens barrel, the second lens is provided with a second optical area and a second structural area, and the second structural area and the second lens barrel form a structural area of the second lens component; a first gap is formed between the top surface of the structural area of the second lens component and the bottom surface of the first structural area; the first adhesive material is positioned in the first gap; the first lens barrel is bonded to the top surface of the structural area of the second lens component through a second adhesive material. The invention further provides a corresponding camera module. According to the invention, the position offset or deformation of the first lens caused by the variation of the first lens barrel can be inhibited, so that the imaging quality of the optical lens and the corresponding camera module is improved.

Description

[0001] related application [0002] This application is a divisional application of the parent case of the Chinese patent application number CN201810403069.7 submitted on April 28, 2018, entitled "Optical Lens, Camera Module and Assembly Method Thereof". technical field [0003] The invention relates to the technical field of optical imaging, in particular, the invention relates to an optical lens, a camera module and an assembly method thereof.
