Abstract
An optical imaging lens may include a first, a second, a third, a fourth, a fifth, a sixth and a seventh lens element positioned in an order from an object side to an image side along an optical axis. Through designing concave and/or convex surface of the lens elements, the optical imaging lens may have improved imaging quality and improved assembly yield while the optical imaging lens may satisfy (|Sag51/ER51|+|Sag52/ER52|)/2≤20.000%, wherein a Sag of an optical boundary of the object-side surface of the fifth lens element is represented by Sag51, a Sag of an optical boundary of the image-side surface of the fifth lens element is represented by Sag52, an effective radius of the object-side surface of the fifth lens element is represented by ER51, and an effective radius of the image-side surface of the fifth lens element is represented by ER52.
