Abstract
An optical imaging lens may include a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, 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, enlarged aperture stop and reduced optical imaging lens length while the optical imaging lens may satisfy D11t61*Fno/ImgH≤1.200 and 110≤V2+V3+V4+V5≤145, wherein a distance from an object side surface of the first lens element to an object side surface of the sixth lens element along the optical axis is represented by D11t61, a f-number of the optical imaging lens is represented by Fno, an image height of the optical imaging lens is represented by ImgH, and Abbe numbers of the second to fifth lens elements are represented by V2, V3, V4, V5.
