Abstract

The present disclosure discloses an optical imaging lens assembly, which includes: a first lens having positive refractive power and a convex object-side surface; a second lens having refractive power, and a concave image-side surface; a third lens having refractive power; a fourth lens having refractive power; and a fifth lens having negative refractive power, a concave object-side surface, and a concave image-side surface. The optical imaging lens assembly satisfies TL/ImgH<1.35; 0.6<R9/f5<1.2 and 0.5<ET5/ET4<1, where TTL is a total length of the optical imaging lens assembly, ImgH is a half diagonal length of an effective pixel area on an imaging plane, f5 is an effective focal length of the fifth lens, R9 is a radius of curvature of the object-side surface of the fifth lens, ET4 and ET5 are edge thicknesses of the fourth and the fifth lenses, respectively.
