Abstract

The invention discloses an optical lens, a camera module and electronic equipment. The optical lens comprises first to fifth lenses from an object side to an image side along an optical axis; the first lens has positive focal power, and the object side surface of the first lens is a convex surface; the second lens has negative focal power, and the image side surface of the second lens is a concave surface; 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; and the fifth lens has focal power, and the object side surface and the image side surface of the fifth lens are a convex surface and a concave surface. The optical lens further meets the relational expression that TTL/ImgH is larger than 1.1 and smaller than 1.3. According to the optical lens, the camera module and the electronic equipment provided by the embodiment of the invention, the design requirements of miniaturization, large image surface and high imaging quality of the optical lens can be met.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens, a camera module and electronic equipment. Background technique [0002] With people's pursuit of thinner and smaller electronic products, the thinner and smaller structural features of optical lenses combined with large image area and high imaging quality shooting effects have gradually become the development trend of optical lenses. In related technologies, in order to achieve a large image surface and achieve higher imaging quality, the aberration of the optical lens is corrected by increasing the number of lenses. However, the increase in the number of lenses not only increases the design and processing of the optical lens. The difficulty is not conducive to the design requirements of the miniaturization of optical lenses. Contents of the invention [0003] The embodiment of the invention discloses an optical lens, a camera module and electronic equ...
