Problems solved by technology
If the precision of the pre-adjustment is insufficient, the relative position between the sub-lenses and the relative position of the sub-lenses of good products need to be adjusted too much, which exceeds the limit of active correction, resulting in the inability to assemble an optical lens or camera module with up to standard imaging quality, which in turn leads to Product yield drops

The present invention provides an optical lens. The optical lens comprises a first lens component, a second lens component and a connecting medium; the first lens component comprises at least one first lens; the second lens component comprises a second lens barrel and at least one second lens mounted on the second lens barrel; the second lens and the first lens jointly form an imageable optical system; at least one of the two lens component has a smooth area, wherein the smooth area is suitable for reflecting a light beam emitted by distance measuring equipment and is positioned on the end surface of the lens component; and the connecting medium is suitable for fixing the first lens component and the second lens component together. The invention further provides a corresponding assemblingmethod of the optical lens, a corresponding image pickup module and an assembling method of the image pickup module. With the optical lens of the invention adopted, height measurement precision can beimproved, so that pre-positioning precision can be improved; distance measurement points can be used as feature points for image recognition, and therefore, pre-positioning and active calibration arefacilitated; and the assembling precision of the optical lens and the image pickup module can be improved.
Description
technical field [0001] 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. 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. However, it is very difficult to achieve the three requirements of high pixel, small size and large aperture in the same camera mold. For example, the compact development of mobile phones and the increase in the pr...
