Abstract
Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises four lens elements positioned in an order from the object side to the image side. Through controlling the convex or concave shape of the surfaces of the lens elements, the thickness of the at least one lens element, an air gap between two lens elements, and a sum of all air gaps between all four lens elements along the optical axis satisfying the relations: (T/G)>4 and (G/T)>1, wherein Tis the thickness of the third lens element, Gis the air gap between the third lens element and the fourth lens element, and Gis the sum of all air gaps between all four lens elements, the optical imaging lens shows better optical characteristics and the total length of the optical imaging lens is shortened.
