Abstract

An optical imaging lens may include a first, a second, a third, and a fourth lens elements positioned in an order from an object side to an image side. Through designing concave and/or convex surfaces of the four lens elements, the optical imaging lens may provide improved imaging quality and optical characteristics while the total length of the optical imaging lens may be shortened and the F-number (Fno) of the optical image lens may be decreased.
