Abstract
An optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens and a fourth lens. Each of the first lens to the fourth lens has refractive power. A total effective focal length f of the optical imaging lens assembly and an effective focal length f1 of the first lens satisfy: 2.0<f1/f<6.5. A center thickness CT3 of the third lens along the optical axis and an edge thickness ET3 of the third lens satisfy: 2.5<CT3/ET3<4.0.
