Problems solved by technology
[0006] However, active calibration of the optical system of the lens itself is a new production process. The actual mass production needs to consider many factors such as the reliability, drop resistance, weather resistance and production cost of the optical lens and camera module, and sometimes requires Yield decline due to various unpredictable factors

Abstract
The invention provides an optical lens. The optical lens comprises a first lens component, a second lens component and a first glue material; a first lens group of the first lens component and a second lens group of the second lens component together form 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 group bears against the inner top surface; the outer top surface comprises a glue distribution surface suitable for arranging the first glue material and an extension surface formed by extending from the glue distribution surface to the central axis of the second lens barrel; a first thickness is formed from the glue distribution surface to the inner top surface, a second thickness is formed from the extension surface to the inner top surface, and the first thickness is greater than the second thickness. The invention further provides a corresponding camera module and an assembling method. The mechanical strength and reliability of a black object of the second lens component can be improved; the yield of the optical lens or the camera module can be improved; miniaturization of camera module is facilitated.
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. Background technique [0002] With the development of terminals such as mobile phones and computers, users have greatly improved their various needs. Especially with the development of mobile phones, users' pursuit of shooting quality has led manufacturers to develop personalized and customized camera modules. , such as large aperture, large wide angle, lens with a large number of lenses to solve aberrations, etc. On the one hand, the optical design is becoming more and more complicated. On the other hand, the reality is that the complex optical system is very sensitive, which poses a big challenge to the manufacturing yield and product quality. Because the optical system of a large aperture and wide-angle camera module is more sensitive, the reliability of its manufacturing process and verif...
