Abstract
The invention provides an optical imaging lens including a first lens element, a second lens element, a third lens element, a fourth lens element, and a fifth lens element from an object side to an image side. The optical imaging lens has a shorter lens length, an enlarged field of view angle, and good thermal stability performance in a good optical performance condition via controlling arrangement of concave and convex curvatures of object-side surfaces or image-side surfaces of the lens elements and controlling relevant parameters via at least one condition expression.
