Abstract

Present embodiments provide for an optical imaging lens. The optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least two inequalities, the optical imaging lens shows better optical characteristics, increases the effective focal length and narrows the angle of view while the total length of the optical imaging lens is shortened.
