Abstract
An optical imaging lens assembly from an object side to an image side includes 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 image-side surface of the first lens element is concave in a paraxial region thereof. The object-side surface of the fourth lens element is convex in a paraxial region thereof. The object-side surface of the fifth lens element is concave in a paraxial region thereof. At least one of the object-side surface and image-side surface of at least one of the first through fifth lens elements has at least one inflection point in an off-axis region thereof. An f-number of the optical imaging lens assembly is Fno, satisfying 1.5<Fno<2.0.
