Abstract
An imaging optical lens assembly includes seven 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, 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 first lens element has negative refractive power. The object-side surface of the first lens element is concave in a paraxial region thereof and the image-side surface of the first lens element is convex in a paraxial region thereof. The object-side surface of the second lens element is convex in a paraxial region thereof. With specific conditions being satisfied, the imaging optical lens assembly can be miniaturized while providing superior image quality.
