Abstract
Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises five lens elements 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 to allow the thickness of the second lens element and the sum of all air gaps between all five lens elements along the optical axis satisfying the relation: 0.20<T2<0.50 (mm) and 0.27<(T2/Gaa)<0.40, the optical imaging lens shows better optical characteristics and the total length of the optical imaging lens is shortened.
