Patent ID: 12000989

Abstract:
The disclosure provides an imaging lens assembly, which sequentially includes, a movable diaphragm, a first lens, a second lens with a refractive power, a third lens with a refractive power, a fourth lens with a positive refractive power and a fifth lens with a refractive power, wherein an effective focal length f1 of the first lens and an effective focal length f4 of the fourth lens meet 1.0<f4/f1<2.3; and TSmin, a distance from the movable diaphragm at a minimum distance from an imaging surface of the imaging lens assembly to an object-side surface of the first lens on the optical axis, TSmax, a distance from the movable diaphragm at a maximum distance from the imaging surface of the imaging lens assembly to the object-side surface of the first lens on the optical axis and CT1, a center thickness of the first lens on the optical axis meet 1.0<(|TSmin|+|TSmax|)/CT1<1.5.
