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, a fifth lens and a sixth lens which are sequentially arranged along an optical axis from an object side to an image side; the first lens, the third lens and the fourth lens have positive refractive power; the object side surface of the first lens is a convex surface; the second lens has negative refractive power; the object side surface of the second lens is a concave surface at the circumference; the fifth lens has negative refractive power, and 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 sixth lens has refractive power; the optical lens satisfies the following relational expression: 1.1<CT1 / SD11<1.8. According to the optical lens, the camera module and the electronic equipment provided by the invention, the miniaturization design of the optical lens can be realized while the high imaging quality of the optical lens is 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 continuous development of camera technology, people have higher and higher requirements for the imaging quality of optical lenses.
