Abstract
An optical imaging lens includes a first lens element to a fifth lens element, and each lens element has an object-side surface and an image-side surface. An optical axis region of the image-side surface of the first lens element is concave, the second lens element has negative refracting power, a periphery region of the image-side surface of the second lens element is convex, the fourth lens element has positive refracting power, and an optical axis region of the object-side surface of the fifth lens element is convex. Lens elements included by the optical imaging lens are only the five lens elements described above, and the optical imaging lens satisfies the relationship of TTL/Fno≥6.000 mm, TTL is the distance from the object-side surface of the first lens element to an image plane along the optical axis, and Fno is a f-number of the optical imaging lens.
