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, increased field of view and increased aperture while the optical imaging lens may satisfy (G34+T4)/AAG≤2.200 and V1+V2+V3+V4≥110.000, wherein an air gap between the third lens element and the fourth lens element along the optical axis is represented by G34, a thickness of the fourth lens element along the optical axis is represented by T4, a sum of the three air gaps from the first lens element to the fourth lens element along the optical axis is represented by AAG and Abbe numbers of the first to the fourth lens elements are represented by V1, V2, V3 and V4.
