Abstract: The optical lenses include a first lenses part including a first lens and a second lenses part including a second lens. The second lens and the first lens constitute an imageable optical system. A first adhesive material is located in a first gap between the first and second lenses parts, the first adhesive material supporting and fixing the first and second lenses parts. The first lenses part has a first bottom surface, and the second lenses part has a second top surface. An adhesive applying area for arranging the first adhesive material is provided on the first bottom surface and/or the second top surface. A first adhesive blocking portion is provided on the first bottom surface and/or a third adhesive blocking portion is provided on the second top surface.

Abstract: The present application provides an optical lens, comprising: a first lens component, a second lens component and a first glue material. A first lens sheet group of the first lens component and a second lens sheet group of the second lens component together constitutes an imageable optical system, wherein a second lens barrel of the second lens component has an outer top surface and an inner top surface, and the second lens sheet group bears against the inner top surface. The outer top surface comprises a glue spreading surface suitable for arranging the first glue material and an extension surface formed by extending from the glue spreading surface to a central axis of the second lens barrel, there is a first thickness from the glue spreading surface to the inner top surface, there is a second thickness from the extension surface to the inner top surface, and the first thickness is greater than the second thickness. The present application further provides a corresponding camera module and an assembling method. The present application can improve the mechanical strength and reliability of the black object of the second lens component, can improve the yield of the optical lens or the camera module, and contributes to the miniaturization of the camera module.

Abstract: A lens group assembly includes a lens barrel and a plurality of lenses. The lenses are embedded in the lens barrel to assemble the lens group, and there is an adhesive material between at least two of the lenses and/or between at least one of the lenses and the lens barrel to reinforce the structural strength of the assembled lens group. A corresponding optical lens, a camera module and a lens group assembling method are also included. Assembling accuracy and assembling stability of the high-sensitivity multi-lens optical system is improved by increasing the adhesion between the lenses. Variation of the optical lens is reduced based on an active calibration process. Adhesive material that might otherwise overflow is accommodated. Defects caused by the assembly of the optical lens are reduced based on the active calibration process, especially the field curvature and peak variation.

Abstract: An optical camera lens includes a first camera lens component including at least one first lens and a second camera lens component including a second lens barrel and at least one second lens mounted in the second lens barrel. The first and second lenses together constitute an imageable optical system. At least one of the two camera lens components has a smooth region located on an end surface of the camera lens component, and a connecting medium for fixing the first and second camera lens components together. A corresponding assembly method of the optical camera lens and a corresponding camera module and an assembly method thereof are also provided. The optical camera lens can improve a pre-positioning accuracy by improving a height measurement accuracy, and can use a distance measuring point as a feature point of image recognition so as to perform pre-positioning and active calibration.
