INTEGRATED LENS BARREL, OPTICAL CAMERA LENS, CAMERA MODULE AND ASSEMBLY METHOD THEREOF

The present application provides an integrated lens barrel including: a cylindrical body having an inner side surface and a central axis; and an inner extension portion extending from the inner side surface to the central axis and the middle of the inner extension portion having a light through hole, the inner extension portion dividing the inner side surface into a first section and a second section, and a top surface of the inner extension portion and the first section forming a first groove suitable for accommodating a first lens group, and a bottom surface of the inner extension portion and the second section forming a second groove suitable for accommodating a second lens group. The present application also provides a corresponding optical camera lens, a camera module, and corresponding assembly methods of optical camera lens and camera module. The present application can reduce source of variation of an optical camera lens based on an active calibration process, thereby improving the imaging quality and yield.
