Document Type and Number:
WIPO Patent Application WO/2021/031725
Kind Code:
A1
Abstract:
An optical lens (1000), comprising a first lens (110) and a second lens component (200). The central area of a first surface (112) of the first lens (110) protrudes to the object side to form a protrusion portion (111), the top surface (113) of the protrusion portion (111) forms an optical area (113a), and a first structural area (115) surrounds the protrusion portion (111). The second lens component (200) comprises a second lens barrel (220) and at least one second lens (210); the top of the second lens barrel (220) is provided with an extension portion (221) extending inwards, so as to form a light inlet hole (222) of the second lens component (200); moreover, the topmost second lens (210) has a third surface (211) located at the object side; the third surface (211) comprises an optical area (211a) in the center, an inner structural area (211b) surrounding the optical area (211a), and an outer structural area (211c); the outer structural area (211c) presses against the bottom surface of the extension portion (221); the inner structural area (211b) is exposed outside the extension portion (221). The first lens (110) is bonded to the second lens component (200), and the outer diameter of the first lens (110) is not greater than the diameter of the light inlet hole (222). According to the optical lens (1000), the diameter of a hole provided on a screen can be reduced without sacrificing the imaging quality. Also disclosed are a camera module, an under-screen camera assembly, a manufacturing method for the optical lens (1000), and a manufacturing method for the camera module.
