Optical lens assembly
An optical lens assembly includes first, second, third, fourth and fifth lens elements arranged in sequence from an object side to an image side along an optical axis. Only the first lens element to the fifth lens element have refracting power, wherein the optical lens assembly satisfies: 3.1≤ALT/AAG, wherein ALT is a sum of thicknesses of the first lens element, the second lens element, the third lens element, the fourth lens element, and the fifth lens element on the optical axis, and AAG is a sum of four air gaps from the first lens element to the fifth lens element on the optical axis.
