Abstract
The invention provides an optical imaging lens. The optical imaging lens comprises a lens barrel, a lens group and a spacing element group, the lens group and the spacing element group are arranged in the lens barrel, the lens group is composed of five lenses, and the five lenses are sequentially a first lens, a second lens, a third lens, a fourth lens and a fifth lens from the object side to the image side; tD / T34 * n3 is more than 5.30 and less than or equal to 5.95; f3 / d3s is greater than or equal to-5.05 and less than-4.55; and CP3b / (d3cm-d3m) is more than or equal to 1.30 and less than 1.80. The five-piece type optical imaging lens solves the problems that a five-piece type optical imaging lens in the prior art meets lens processing feasibility and assembling stability, consequently, a middle lens gap is large, and stray light is generated.
