Abstract

The invention discloses an optical lens, a camera module and electronic equipment, and the optical lens comprises a first lens with positive refractive power, a second lens with negative refractive power, a third lens with positive refractive power, a fourth lens with negative refractive power and a fifth lens with positive refractive power, which are sequentially arranged from an object side to an image side along an optical axis; the second lens element with refractive power has a convex object-side surface and a concave image-side surface in a paraxial region, respectively. The third lens element with positive refractive power has an object-side surface and an image-side surface being convex in a paraxial region. The fourth lens element with negative refractive power has a convex object-side surface and a concave image-side surface in a paraxial region, respectively. A fifth lens element with refractive power having an object-side surface being convex in a paraxial region thereof; a sixth lens element with refractive power; a seventh lens element with refractive power having a convex object-side surface and a concave image-side surface in paraxial regions, respectively; the optical lens satisfies the following relational expressions: 2.5 lt; fno * TTL / ImgHlt; and 3.5. According to the optical lens, the camera module and the electronic equipment provided by the invention, the miniaturization of the optical lens can be realized, and meanwhile, a large-aperture shooting effect is achieved.

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] Large-aperture lenses are favored by the market because of their high relative illuminance, wide range of adaptable light, and good blur effects, and are widely used in electronic equipment. However, in order to achieve the function of large aperture, the optical lens is usually large in size, which cannot meet the miniaturization design requirements of electronic equipment. Contents of the invention [0003] The embodiment of the invention discloses an optical lens, a camera module and an electronic device, which can realize the miniaturization of the optical lens and have the shooting effect of a large aperture. [0004] In order to achieve the above object, on the one hand, the present invention discloses an optical lens, the optical lens sequentially includes from the object si...
