Abstract
An optical imaging lens includes a first lens element to a seventh lens element, and each lens element has an object-side surface and an image-side surface. The second lens element has negative refracting power, an optical axis region of the object-side surface of the fifth lens element is concave, and an optical axis region of the object-side surface of the seventh lens element is convex. Lens elements included by the optical imaging lens are only the seven lens elements described above, and the following relationships: V5+V6+V7≥140.000, (ImgH+D61t72)/D11t42≥2.400, V4≥30.000 are satisfied.
