Abstract

The present disclosure discloses an optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens having refractive power, a concave object-side surface and a concave image-side surface; a second lens having positive refractive power; a third lens having refractive power and a convex object-side surface; a fourth lens having positive refractive power; and a fifth lens having negative refractive power. An effective focal length f1 of the first lens and a radius of curvature R1 of the object-side surface of the first lens satisfy 0.7≤f1/R1<1.5.
