OPTICAL LENS ASSEMBLY, CAMERA MODULE, AND ASSEMBLING METHOD THEREFOR

The present application provides an optical lens, comprising: a first lens component comprising at least one first lens sheet; a second lens component comprising a second lens barrel and at least one second lens sheet mounted in the second lens barrel, wherein the at least one second lens sheet and the at least one first lens sheet together constitute an imageable optical system, wherein at least a part of the outer side surface of the second lens sheet at the bottommost end among the at least one second lens sheet is exposed to the outside of the second lens barrel, and the top surface of the second lens sheet at the bottommost end bears against the bottom surface of the second lens barrel; and a connecting medium adapted to fix the first lens component and the second lens component together. The present application further provides a corresponding camera module and optical lens and camera module assembly methods. The present application can effectively reduce the size of the optical lens in the direction perpendicular to the optical axis on the premise of an established optical design, and at the same time can ensure the imaging quality of the optical lens.
