Problems solved by technology

Among them, the improvement of the portability of electronic equipment puts forward higher requirements for the thickness of the camera lens. At the same time, the use of chips with a large image surface has become an inevitable trend. The support leads to the decline of imaging image quality and deterioration of manufacturability; especially for ultra-wide-angle camera lenses, because conventional ultra-wide-angle camera lenses use a quasi-symmetrical structure in the middle of the aperture, it is difficult to fully miniaturize the ultra-wide-angle camera lens, so the improvement The thinness and lightness of the ultra-wide-angle camera lens and the problems of maintaining good imaging quality need to be solved urgently

Abstract

The invention discloses an optical lens, a camera module and electronic equipment. The optical lens comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens which are sequentially arranged along an optical axis from an object side to an image side, the first lens has positive focal power, and the object side surface and the image side surface of the first lens are a convex surface and a concave surface near the optical axis respectively; the second lens has positive focal power, the image side surface of the second lens is a convex surface at the light inlet axis, and the third lens has focal power; the fourth lens has focal power, and the object side surface of the fourth lens is a convex surface near the optical axis; and the fifth lens has focal power, the object side surface and the image side surface of the fifth lens are respectively a convex surface and a concave surface near the optical axis, and the optical lens meets the relational expression: 1.2 < SD11 / SD21 < 1.6. According to the optical lens, the camera module and the electronic equipment, the ultra-wide-angle imaging effect can be realized on the basis of considering the miniaturization and light and thin design of the optical lens.

Description

technical field [0001] The present application relates to the technical field of optical imaging, in particular to an optical lens, a camera module and electronic equipment. Background technique [0002] In recent years, various electronic devices equipped with imaging lenses (including digital cameras, smart phones, notebook computers, tablet computers, etc.) are rapidly developing and popularizing. Among them, the improvement of the portability of electronic equipment puts forward higher requirements for the thickness of the camera lens. At the same time, the use of chips with a large image surface has become an inevitable trend. The support leads to the decline of imaging image quality and deterioration of manufacturability; especially for ultra-wide-angle camera lenses, because conventional ultra-wide-angle camera lenses use a quasi-symmetrical structure in the middle of the aperture, it is difficult to fully miniaturize the ultra-wide-angle camera lens, so the improveme...
