  • Publication number: 20250138284
    Abstract: An image capturing lens assembly includes six lens units which are, in order from an object side to an image side along an optical path: first through sixth lens units. Each lens unit of the first through third lens units and the fifth through sixth lens units is a single lens element. The fourth lens unit is a single lens element or is composed of two lens elements, and the fourth lens unit at least includes a front lens element. The total number of lens elements of the image capturing lens assembly is six to seven. The first lens unit has an image-side surface being concave in a paraxial region thereof. The third lens unit has an object-side surface being convex in a paraxial region thereof. The front lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof.

  • Patent number: 12228703
    Abstract: An optical imaging system includes seven 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, a sixth lens element and a seventh lens element. Each of the seven lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The seventh lens element has negative refractive power, and the object-side surface of the seventh lens element is concave in a paraxial region thereof. At least one of the object-side surface and the image-side surface of at least one lens element of the optical imaging system has at least one inflection point in an off-axis region thereof.
