Document Type and Number:
WIPO Patent Application WO/2019/029331
Kind Code:
A1
Abstract:
Provided in the present invention is an assembly method for an optical lens, comprising: preparing a first sub-lens and a second sub-lens, the first sub-lens comprising a first lens barrel and at least one first lens sheet, while the second sub-lens comprises a second lens barrel and at least one second lens sheet; arranging the first sub-lens on an optical axis of the second sub-lens to form an optical system that may be imaged; by means of causing the first sub-lens to move relative to the second sub-lens in the optical-axis direction, an actually-measured image plane from imaging the optical system matching a target plane; and connecting the first sub-lens and the second sub-lens such that a relative distance between the first sub-lens and the second sub-lens in the optical-axis direction remains unchanged. Further provided in the present invention are a corresponding optical lens, as well as a camera module and an assembly method therefor. The present invention may effectively reduce field curvature, may improve a process capability index, and may loosen requirements in the accuracy of each component and the accuracy in the assembly thereof.
