  • Patent number: 9261672
    Abstract: The present embodiments provide a mobile device and an optical imaging lens thereof. The optical imaging lens comprises a first lens element, an aperture, a second lens element, a third lens element, a fourth lens element, and a fifth lens element positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces and/or the refracting power of the lens elements, the total length of the optical image lens is shortened, the field of view is broadened, and the better image performance is maintained. Above all, the optical imaging lens of the present invention is capable of shortening the total length of the optical imaging lens efficiently, enlarging the half field of view of the optical imaging lens, and showing better optical characteristics.
