Abstract
the An optical imaging lens includes four lens elements positioned in order from the object side to the image side of the optical imaging lens. Through controlling the convex or concave shape of the surfaces of lens elements, the refracting power of lens elements, the thickness of the at least one lens element, one or more air gaps between lens elements along the optical axis, and a half field of view HFOV of the optical imaging lens, an embodiment satisfies the relation: 4.21≦T/(G12×tan(HFOV))≦7.55, for which Tis the thickness of the third lens element and Gis the air gap between the first lens element and the second lens element. The optical imaging lens provided by embodiments of the present invention has better optical characteristics and a reduced total length in comparison to conventional lenses.
