  • Publication number: 20250116846
    Abstract: An optical imaging lens assembly includes a lens barrel, first to seventh lenses sequentially arranged along an optical axis from an object side to an image side, a fifth spacing piece and a sixth spacing piece. The fifth spacing piece is placed between the fifth lens and the sixth lens, and the sixth spacing piece is placed between the sixth lens and the seventh lens. A maximal thickness CP6 of the sixth spacing piece along a direction of the optical axis is greater than a center thickness CT6 of the sixth lens on the optical axis. An inner diameter d5s of an object-side surface of the fifth spacing piece, an inner diameter d6s of an object-side surface of the sixth spacing piece, and a spacing distance T56 between the fifth lens and the sixth lens on the optical axis satisfy: 4.5<(d6s?d5s)/T56<8.0.

  • Publication number: 20240192486
    Abstract: A camera module. The camera module includes a lens barrel, and a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens having a negative refractive power provided in the lens barrel, and a spacer arranged between the sixth lens and the seventh lens on the optical axis of the camera module. An effective focal length f7 of the seventh lens, an inner diameter d6m of an image-side surface of the sixth spacer, an air interval T67 between the sixth lens and the seventh lens along the optical axis, and a maximum thickness CP6 of the sixth spacer satisfy: 1.0<|d6m/f7|+T67/CP6<8.5.

  • Publication number: 20230400662
    Abstract: The present disclosure discloses an optical imaging lens assembly. The optical imaging lens assembly includes a lens barrel and a lens group assembled in the lens barrel. The lens group along an optical axis from an object side to an image side sequentially includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens having refractive powers. An outer diameter of the seventh lens is greater than an outer diameter of any one of the first lens to the sixth lens; and three lenses of the first lens to the sixth lens have positive refractive powers, and other three lenses of the first lens to the sixth lens have negative refractive powers.
