Problems solved by technology

In fact, these methods cannot effectively solve the aforementioned problems.
Because there are many factors affecting field curvature, which exist in multiple components, the control of each factor has the limit of manufacturing accuracy. If the strength of each component is simply increased, the lifting capacity is limited, the lifting cost is high, and the residual field curvature cannot Meet the market's increasing demand for imaging quality

Abstract

The invention provides an optical lens assembly method, and the method comprises the steps: preparing a first sub-lens and a second sub-lens, wherein the first sub-lens includes a first lens cone andat least one first lens, and the second sub-lens includes a second lens cone and at least one second lens; arranging the first sub-lens on an optical axis of the second sub-lens to form an imageable optical system; enabling the first sub-lens to move in the direction of the optical axis relative to the second sub-lens, and enabling an actual measurement image plane of the optical system to be matched with a target plane; connecting the first sub-lens and the second sub-lens so as to enable the relative distance between the first sub-lens and the second sub-lens to remain unchanged in the direction of the optical axis. The invention also provides a corresponding optical lens, a camera module and an assembly method thereof. The optical lens can effectively reduce the field curvature, can improve the process capability index, and can enable the requirements of the accuracy of each component and its assembly precision to be low.

Description

technical field [0001] The present invention relates to the field of optical technology, in particular, the present invention relates to solutions of optical lenses and camera modules. Background technique [0002] With the popularization of mobile electronic devices, related technologies of camera modules used in mobile electronic devices to help users acquire images (such as video or images) have developed rapidly and improved rapidly, and in recent years, camera modules Groups have been widely used in many fields such as medical treatment, security, industrial production and so on. [0003] In order to meet more and more extensive market demands, high pixel, small size, and large aperture are irreversible development trends of existing camera modules. The market has put forward higher and higher demands on the imaging quality of camera modules. Factors affecting the resolution of a camera module with a given optical design include the quality of the optical imaging lens...
