Claim 12:
13. An optical imaging lens assembly, sequentially from an object side to an image side along an optical axis, comprising: a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, each of which has refractive power,
wherein,
an object-side surface of the first lens is a convex surface, and an image-side surface of the first lens is a concave surface;
an image-side surface of the second lens is a concave surface; and
an object-side surface of the sixth lens is a convex surface,
wherein 0.6<(R2−R1)/f<1.1,
where R2 is a radius of curvature of the image-side surface of the first lens, R1 is a radius of curvature of the object-side surface of the first lens, and f is a total effective focal length of the optical imaging lens assembly, and
wherein 0<(R7+R9)/(R7−R9)<1,
where R7 is a radius of curvature of an object-side surface of the fourth lens, and R9 is a radius of curvature of an object-side surface of the fifth lens.
