  • Patent number: 10606043
    Abstract: An optical imaging lens includes first, second, third, fourth, fifth and sixth lens elements arranged in sequence from an object side to an image side along an optical axis. The third lens element is a first lens having a refracting power and sequentially counted from an aperture stop toward the object side. The fourth lens element is a first lens sequentially counted having a refracting power and from the aperture stop toward the image side. At least one of the third lens element and the fourth lens element has a positive refracting power and is a glass material. The optical imaging lens is complied with: 2.4?(G1+G2)/T6.
    Type: Grant

  • Patent number: 10437013
    Abstract: Present embodiments provide for an optical imaging lens system. The optical imaging lens system may comprise at least four lens elements positioned sequentially from an object side to an image side. By controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least three inequalities, the optical imaging lens system may exhibit better optical characteristics and the total length of the optical imaging lens system may be shortened.

  • Patent number: 10133032
    Abstract: Present embodiments provide for an optical imaging lens. The optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and seven lens element positioned in an order from an object side to an image side. Through the arrangement of convex or concave surfaces of the seven lens elements, the length of the optical imaging lens may be shortened while providing better optical characteristics and imaging quality.
