Optical imaging lens assembly

An optical imaging lens assembly, comprising, sequentially along an optical axis from an object side to an image side:

• a stop;
• a first lens having positive refractive power;
• a second lens having negative refractive power;
• a third lens having negative refractive power;
• a fourth lens having positive refractive power;
• a fifth lens having negative refractive power;
• and
• a sixth lens having negative refractive power, and an image-side surface of the sixth lens is convex,
• wherein a number of lenses having refractive powers in the optical imaging lens assembly is six, the first lens to the sixth lens include two glass aspheric lenses, 4.5<T23/T45<9.0, −3.0<f3/(R5+R6)<−2.0, and TTL/f<1.0,
• where T23 is a spaced interval between the second lens and the third lens along the optical axis, T45 is a spaced interval between the fourth lens and the fifth lens along the optical axis, f3 is an effective focal length of the third lens, R5 is a radius of curvature of an object-side surface of the third lens, R6 is a radius of curvature of an image-side surface of the third lens, TTL is a distance along the optical axis from an object-side surface of the first lens to an image plane of the optical imaging lens assembly, and f is an effective focal length of the optical imaging lens assembly.
