Abstract

An optical imaging lens includes a plurality of lens elements arranged in order from an object side to an image side along an optical axis, and each lens element has an object-side surface and an image-side surface. There is at least one variable gap between the lens elements, and one of the lens elements closest to the object side has positive refracting power. The optical imaging lens satisfies: ΔG/Gv≦0.1. Here, ΔG is an absolute value of a difference between a first value and a second value of the length of the at least one variable gap along the optical axis when an object having an infinite object distance and an object having an object distance of 500 millimeters are focused respectively, and Gv is the second value.
