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, shortened length, increased effective focal length and lowered f-number while the optical imaging lens may satisfy HFOV*Fno/EFL≤2.400, wherein a half field of view of the optical imaging lens is represented by HFOV, a f-number of the optical imaging lens is represented by Fno, and an effective focal length of the optical imaging lens is represented by EFL.
