  • Patent number: 11009684
    Abstract: An optical imaging lens includes a first, a second, a third, a fourth, a fifth, a sixth, a seventh and an eighth lens elements from an object side to an image side in order along an optical axis. The first lens element and the second lens element both have positive refracting power. An optical axis region of an object-side surface of the fifth lens element is concave. A periphery region of an image-side surface of the fifth lens element, an optical axis region of an object-side surface of the sixth lens element and an optical axis region of an object-side surface of the seventh lens element are convex. Materials of the third, the fourth and the eighth lens elements are plastic. The eight lens elements are the only lens elements having refracting power in the optical imaging lens.

  • Patent number: 10830996
    Abstract: The present disclosure provides an optical imaging lens. The optical imaging lens may comprise six lens elements positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens may shorten system length and enlarge view angle and aperture size.

  • 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.

    Abstract: An optical imaging lens includes a first, a second, a third, a fourth, a fifth, a sixth, a seventh and an eighth lens elements from an object side to an image side in order along an optical axis. The first lens element and the second lens element both have positive refracting power. An optical axis region of an object-side surface of the fifth lens element is concave. A periphery region of an image-side surface of the fifth lens element, an optical axis region of an object-side surface of the sixth lens element and an optical axis region of an object-side surface of the seventh lens element are convex. Materials of the third, the fourth and the eighth lens elements are plastic. The eight lens elements are the only lens elements having refracting power in the optical imaging lens.
