Abstract

An optical imaging lens includes a first lens element, a second lens, an aperture stop, a third lens element and a fourth lens element from an object side to an image side in order along an optical axis, and each lens element has an object-side surface and an image-side surface. An optical axis region of the object-side surface of the second lens element is convex. Only the above-mentioned four lens elements of the optical imaging lens have refracting power to satisfies the relationship: HFOV≤15.000°, 3.000≤TL/(G12+T2+G23) and TTL/BFL≤3.500.
