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 positive refractive power with a convex image-side surface;
a second lens having negative refractive power with a concave object-side surface; and
a third lens having a positive refractive power,
wherein 1.0<CT1/DT11<2.0,
where CT1 is a center thickness of the first lens along the optical axis, and DT11 is a maximum effective radius of an object-side surface of the first lens; and
ETL/EIN<1.5,
where ETL is a distance parallel to the optical axis from the object-side surface of the first lens to an imaging plane of the optical imaging lens assembly at a 1/2 entrance pupil diameter, and EIN is a distance parallel to the optical axis from the object-side surface of the first lens to an image-side surface of the third lens at the 1/2 entrance pupil diameter.
