Abstract
An optical imaging lens includes, in order from an object side to an image side, first, second, third, fourth, fifth, sixth, and seventh lens elements arranged along an optical axis. The object-side surface of the first lens element has a convex portion and the image-side surface has a concave portion. The image-side of the third lens element is a concave surface. The object-side surface of the fourth lens element has a concave portion and the image-side surface of the fourth lens element has a convex portion. The image-side surface of the sixth lens element has a convex portion. The object-side surface of the seventh lens element has a convex portion and the image-side surface has a convex portion. The optical imaging lens only has seven lens elements having a refractive power.
