Abstract

The invention discloses an optical lens, a camera module and electronic equipment, and the optical lens comprises a first lens which is provided with positive focal power from an object side to an image side along an optical axis, the object side surface of the first lens is a convex surface, and the image side surface of the first lens is a concave surface; the object side surface of the second lens is a convex surface, and the image side surface of the second lens is a concave surface; the object side surface of the third lens is a convex surface; the image side surface of the fourth lens is a convex surface; the fifth lens has negative focal power; the sixth lens has positive focal power; and the object side surface of the seventh lens is a convex surface, and the image side surface of the seventh lens is a concave surface. The optical lens also satisfies the relational expression: 7 mmlt; f * tan (HFOV) lt; and the thickness is 7.5 mm. According to the optical lens, the camera module and the electronic equipment provided by the embodiment of the invention, the design requirements of large image surface, large wide angle and miniaturization 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 structural characteristics of ultra-thin and miniaturized optical lenses and the shooting effect of large image area and wide angle have gradually become the development trend of optical lenses. However, the five-element optical lens and the six-element optical lens used in the related art can no longer meet people's requirements for large image area, wide angle and ultra-thin miniaturization of the optical lens. At present, how to realize the design requirements of large image area, large wide angle and ultra-thin miniaturization of optical lenses is still a technical problem that needs to be solved urgently in the field of optical imaging technology. Contents of the invention [0003] The embodiment of the inve...
