1. An optical imaging lens, comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens in sequence along an optical axis from an object side to an image side, wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens respectively have a negative diopter, a positive diopter, a negative diopter, a positive diopter, a negative diopter and a positive diopter; the optical imaging lens has a total of six lenses; the first lens to the fifth lens are aspheric surface lenses, and the sixth lens is a metalens,
wherein the optical imaging lens satisfies a conditional expression of TTL/EFL<0.8, where TTL is a distance from an object side surface of the first lens to an image plane on the optical axis, and EFL is an effective focal length of the optical imaging lens.
