Abstract
An optical imaging lens assembly from an object side to an image side along an optical axis sequentially includes: a first lens, having a positive refractive power, its object-side surface is convex and its image-side surface is concave; a second lens, having a refractive power, its object-side surface is convex and its image-side surface is concave; a third lens, having a refractive power; a fourth lens, having a refractive power and its object-side surface is concave; a fifth lens, having a positive refractive power, its object-side surface is concave and its image-side surface is convex; and a sixth lens, having a negative refractive power and its object-side surface is concave. A total effective focal length f of the optical imaging lens assembly and a radius of curvature R12 of an image-side surface of the sixth lens satisfy: 0≤f/R12≤1.5.
