Optical imaging lens assembly

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 prism having an incident surface, a reflecting surface, and an exit surface, wherein an angle between the reflecting surface and the optical axis is 45°;
• a stop;
• a second lens having positive refractive power;
• a third lens having refractive power;
• a fourth lens having positive refractive power;
• and
• a fifth lens having negative refractive power,
• wherein −5.50<f1/f<−1.50, where f1 is an effective focal length of the first lens, and f is a total effective focal length of the optical imaging lens assembly,
• wherein 4.00<(DT51+DT52)/(DT52−DT51)<11.00, where DT51 is a maximum effective radius of an object-side surface of the fifth lens, and DT52 is a maximum effective radius of an image-side surface of the fifth lens, and
• wherein a distance on the axis between the incident surface and the reflecting surface of the prism is greater than or equal to 1.41 mm, the distance on the axis between the incident surface and the reflecting surface of the prism being equal to a distance on the axis between the reflecting surface and the exit surface of the prism, and a number of lenses having refractive powers included in the optical imaging lens assembly is five.
