IMAGING OPTICAL LENS ASSEMBLY, IMAGE CAPTURING UNIT AND ELECTRONIC DEVICE

원문 (중국어)

An imaging optical lens assembly 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. The first lens element has negative refractive power. The second lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. The fifth lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. The sixth lens element has an image-side surface being concave in a paraxial region thereof. The seventh lens element has an image-side surface being concave in a paraxial region thereof and having at least one inflection point.
