1. An optical imaging lens assembly, sequentially from an object side to an image side of the optical imaging lens assembly along an optical axis, comprising:
a first lens having negative refractive power;
a first prism having an incident surface, a reflecting surface, and an exit surface, and an angle between the reflecting surface of the first prism and the optical axis being 45°;
a stop;
a second lens having positive refractive power;
a third lens having refractive power;
a fourth lens having positive refractive power;
a fifth lens having negative refractive power; and
a second prism having an incident surface, a reflecting surface, and an exit surface, and an angle between the reflecting surface of the second prism and the optical axis being 45°,
wherein
1.00<f34/f23<2.50,
f23 is a combined focal length of the second lens and the third lens,
f34 is a combined focal length of the third lens and the fourth lens,
7.00<1345/R10<12.00, and
f345 is a combined focal length of the third lens, the fourth lens, and the fifth lens, and R10 is a radius of curvature of an image-side surface of the fifth lens.
