Abstract
An optical imaging lens includes a first lens element to an eighth lens element and each lens element has an object-side surface and an image-side surface. The second lens element has negative refracting power, a periphery region of the image-side surface of the third lens element is convex, the fourth lens element has positive refracting power, an optical axis region of the object-side surface of the sixth lens element is convex, and an optical axis region of the object-side surface of the eighth lens element is concave. Lens elements included by the optical imaging lens are only eight lens elements described above to satisfy υ3+υ4+υ5+υ6+υ7≤195.000 and (ImgH+BFL)/Fno≥4.000 mm.
