Abstract

The present disclosure discloses an optical imaging lens assembly. The optical imaging lens assembly includes, sequentially along an optical axis from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The first lens has a positive refractive power, and each of the second lens, the third lens, and the sixth lens has a negative refractive power. At least one of the fourth lens or the fifth lens has a positive refractive power. The object-side surface of the first lens and the image-side surface of the fourth lens are convex surfaces. The image-side surface of the second lens and the image-side surface of the sixth lens are concave surfaces. A total effective focal length f of the optical imaging lens assembly and a radius of curvature R9 of an object-side surface of the fifth lens satisfy: f/|R9|≤0.35.
