Abstract
An optical imaging lens device includes, in order from an object side to an image side: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, the object-side and image-side surfaces of the sixth lens element being provided with at least one inflection point, at least one of the object-side and image-side surfaces of the sixth lens element having a sagittal height in a first axis, a sagittal height in a second axis and a sagittal height in a third axis, and at least two of these sagittal heights being different. The optical imaging lens device may meet the needs of miniaturization, wide field of view and low distortion.
