Abstract

The invention provides an optical imaging lens and electronic equipment. The optical imaging lens successively includes a first lens with focal power, a second lens with the focal power, a third lenswith the focal power and more than two follow-up lens with the focal power in a light axis direction from the object side to the image side; and the distance TTL on the light axis between the object face of the first lens and the imaging face of the optical imaging lens and the total effective focal length f of the optical imaging lens are satisfied: TTL / f is less than 1 and an opticator of more than one lens in lens included by the optical imaging lens is cut on the Y axe, the largest effective radius DY on the Y axe of a cut lens and the largest effective radius DX on the X axe are satisfiedthat DY / DX is greater than 0.5 and less than 1.0, and the X axe is perpendicular to the Y axe.

Description

technical field [0001] The embodiments of the present application relate to the field of optical elements, and in particular, relate to an optical imaging lens and an electronic device. Background technique [0002] Generally, the ultra-telephoto optical imaging lens needs to obtain sufficient luminous flux (that is, a large aperture) due to its long focal length. Therefore, not only the TTL of the entire lens will become longer, but the diameter of the entrance pupil of the lens will also become larger. In this case, the height of the lens increases. Even if the lens is reduced by prism steering, the size of the lens in the Y-axis direction will still be relatively large, which is difficult to meet the height limit requirements of the lens module. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the present application provides an optical imaging lens and electronic equipment. [0004] One aspect of the present application p...
