  • Patent number: 10761298
    Abstract: An optical imaging lens may comprise a first, a second, a third, a fourth, a fifth, a sixth and a seventh lens elements sequentially from an object side to an image side along an optical axis, and each of the first, second, third, fourth, fifth, sixth and seventh lens elements may have an object-side surface facing toward the object side and allowing imaging rays to pass through as well as an image-side surface facing toward the image side and allowing the imaging rays to pass through. The optical imaging lens may comprise no other lens elements having refracting power beyond the first, second, third, fourth, fifth, sixth and seventh lens elements. Through designing concave and/or convex surfaces of the four lens elements, the optical imaging lens may provide improved imaging quality and optical characteristics while the total length of the optical imaging lens may be shortened.
