Abstract
An optical imaging lens includes a first lens element, a second lens, a third lens element and a fourth lens element from an object side to an image side in order along an optical axis, and each lens element has an object-side surface and an image-side surface. 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 image-side surface of the second lens element is convex, and the fourth lens element has negative refracting power, and an optical axis region of the object-side surface of the fourth lens element is convex. The lens elements included by the optical imaging lens are only the four lens elements described above. The optical imaging lens satisfies the following conditions: υ1+υ4≤100.000 and TTL/T1≤5.500.
