Abstract
An imaging lens including a metalens and a light-turning element in sequence from an object side to an image side along an optical axis. The light-turning element includes an incident surface, a first reflecting surface, a second reflecting surface, and a light-emitting surface in sequence from the object side to the image side along the optical axis. When entering the imaging lens, rays may be reflected at the first reflecting surface and the second reflecting surface in sequence. The first reflecting surface and the second reflecting surface are inner surfaces of the light-turning element.
