Abstract

The invention discloses an optical lens, a camera module and electronic equipment. The optical lens comprises the following lens elements which are sequentially arranged from an object side to an image side along an optical axis: a first lens element with positive focal power having a convex object side surface and a concave image side surface; a second lens element with negative focal power having a convex object side surface and a concave image side surface; a third lens element with focal power; a fourth lens element with focal power having a concave object side surface and a convex image side surface; a fifth lens element; a sixth lens element; and a seventh lens element with negative focal power having a concave object side surface and a concave image side surface. The optical lens also satisfies the relational expression: 2.30 < FNO * TTL / ImgH < 2.38. 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 aperture, large image plane 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 the rapid development of technology, consumers have higher and higher requirements for the imaging quality of mobile electronic products such as smartphones. In related technologies, an optical lens with a large image surface can better cooperate with a photosensitive element to obtain higher resolution, thereby improving the shooting quality of electronic products and improving the resolution and definition of electronic products, thereby realizing High imaging quality requirements of electronic equipment. However, the size of the image plane of the current optical lens is insufficient, and it is difficult to match the photosensitive element with a larger photosensitive surface, which makes it difficult to effectively improve the pixels of electronic products.
