Abstract

An optical imaging lens sequentially includes a first, a second, a third, a fourth, a fifth, and a sixth lens elements from an object side to an image side along an optical axis. Each of the lens elements includes an object-side surface and an image-side surface. The second lens element has negative refracting power. A periphery region of the object-side surface of the fourth lens element is convex. A periphery region of the image-side surface of the fifth lens element is convex. The optical imaging lens satisfies following conditions: HFOV≤45°; 2.000≤D1/D2, and TTL/T6≤6.300.
