  • Imaging optical lens assembly including five lenses +?++?, ?++?, ??++?, +?+++, +++?+, +?+?+, +?+??, or ?++?+ of refractive powers, imaging apparatus and electronic device
    Patent number: 11899172
    Abstract: An imaging optical lens assembly includes five lens elements, which are, in order from an object side to an image side along an optical path, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. Each of the five lens elements has an object-side surface towards the object side and an image-side surface towards the image side. The third lens element has positive refractive power. At least one of the object-side surface and the image-side surface of at least one of the five lens elements includes at least one critical point in an off-axis region thereof.

  • Imaging optical lens assembly, imaging apparatus and electronic device
    Patent number: 11860447
    Abstract: An imaging optical lens assembly includes five lens elements. The five lens elements in order from an object side to an image side along an optical path are a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. Each of the five lens elements has an object-side surface facing the object side and an image-side surface facing the image side. The first lens element has positive refractive power, the second lens element has negative refractive power and the third lens element has negative refractive power. With specific conditions being satisfied, the imaging optical lens assembly can be miniaturized while providing good image quality.

  • Image capturing lens assembly, image capturing unit and electronic device
    Patent number: 11703665
    Abstract: An image capturing lens assembly includes six lens elements which are, in order from an object side to an image side along an optical path: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. The fourth lens element with positive refractive power has an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof. The sixth lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. At least one of an object-side surface and an image-side surface of at least one lens element has at least one inflection in an off-axis region thereof.
