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 positive refractive power with a convex object-side surface and a concave image-side surface;
• a second lens having negative refractive power with a concave image-side surface;
• a third lens having refractive power with a convex object-side surface and a concave image-side surface;
• a fourth lens having refractive power;
• a fifth lens having refractive power;
• a sixth lens having refractive power;
• a seventh lens having positive refractive power with a convex object-side surface;
• and
• an eighth lens having negative refractive power with a concave object-side surface and a concave image-side surface,
• wherein 5.80 mm<ImgH, and
• 3.00<(CT5+CT7)/(CT7−CT5)<7.00,
• where ImgH is half of a diagonal length of an effective pixel area on an imaging plane of the optical imaging lens assembly, CT5 is a center thickness of the fifth lens along the optical axis, and CT7 is a center thickness of the seventh lens along the optical axis.
