Abstract
An optical imaging lens includes a first lens element, a second lens element, a third lens element and a fourth lens element. The optical-axis region of the image-side surface of the first lens element is concave, the periphery region of the image-side surface of the second lens element is convex, a third lens has positive refracting power and the optical-axis region of the object-side surface of the fourth lens element is convex. The Abbe number of the first lens element is υ, the Abbe number of the second lens element is υ, the Abbe number of the third lens element is υand the Abbe number of the fourth lens element is υto satisfy υ≤30.000 and υ≤120.000.
