Abstract

The present disclosure discloses an optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens having negative refractive power; a first prism including 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 including 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°. A total effective focal length f and a maximum field-of-view FOV of the optical imaging lens assembly satisfy: 2.50 mm<f*tan2(FOV/2)<4.00 mm.
