Abstract
An optical imaging lens includes a first lens element, a second lens element, a third lens element and a fourth lens element. The first lens element has positive refracting power, an optical-axis region of the object-side surface of the second lens element is convex, a periphery region of the object-side surface of the second lens element is convex, and an optical-axis region of the image-side surface of the second lens element is convex. The Abbe number of the first lens element is υ1, the Abbe number of the second lens element is υ2 and the Abbe number of the third lens element is υ3 to satisfy 61.119≤υ1+υ2+υ3≤96.733.
