Abstract
An optical lens (10), a lens module (100), and a terminal (1000) are provided. The optical lens (10) includes a first constituent element (S1), a second constituent element (S2), a third constituent element (S3), and a fourth constituent element (S4) arranged from an object side to an image side, and each of the constituent elements includes at least one lens element. The optical lens (10) satisfies the following relations: 9.08≤BFL≤11.745; and 0.6≤BFL/TTL≤0.67. In this way, the optical lens (10) can obtain a long back focal length BFL, and long-focus photographing of the optical lens (10) is implemented. In addition, an axial thickness TTL1 of a plurality of lenses of the optical lens (10) is small, so that a thickness of the terminal (1000) including the optical lens (10) may also be small.
