Abstract

The application discloses an optical imaging lens assembly including sequentially from an object side to an image side, a first lens with a positive refractive power and a convex object side surface; a second lens with a refractive power and a concave image side surface; a third lens with a refractive power; a fourth lens with a positive refractive power; a fifth lens with a negative refractive power and a concave object side surface; and a sixth lens with a negative refractive power and a concave object side surface, wherein a space interval T34 between the third lens and the fourth lens along an optical axis and a space interval T45 between the fourth lens and the fifth lens along the optical axis satisfy 0.2<T34/T45<0.6.
