LENS SET ASSEMBLY, OPTICAL LENS, CAMERA MODULE, AND LENS SET ASSEMBLY METHOD

摘要

The present application provides a lens group assembly including: a lens barrel; and a plurality of lenses, wherein the plurality of lenses are embedded in the lens barrel to assemble the lens group, and there is an adhesive material between at least two lenses of the plurality of lenses and/or between at least one lens of the plurality of lenses and the lens barrel to reinforce the structural strength of the assembled lens group. The invention also provides a corresponding optical lens, a camera module and a lens group assembling method. The invention can improve the assembling accuracy and assembling stability of the high-sensitivity multi-lens optical system by increasing the adhesion between the lenses; it can reduce the variation of the optical lens based on an active calibration process; it can accommodate the adhesive material that might otherwise overflow; it can reduce the defects caused by the assembly of the optical lens based on the active calibration process, especially the field curvature and peak variation.
