Abstract
An imaging lenses and an imaging device are provided, the imaging lenses includes a first imaging lens, a second imaging lens and a third imaging lens which are arranged at intervals in sequence, wherein the first imaging lens, the second imaging lens and the third imaging lens satisfy 1.0<Fno1<Fno2<Fno3<3.0; 5.0 mm>F1>F2>F3>1.0 mm; P1<P2<P3; wherein Fno1 is an aperture number of the first imaging lens, Fno2 is an aperture number of the second imaging lens, Fno2 is an aperture number of the third imaging lens, F1 is an effective focal length of the first imaging lens, F2 is an effective focal length of the second imaging lens, F3 is an effective focal length of the third imaging lens. The disclosure solves the problem in the related art that a resolution of light of 3D structure the imaging device is low in a distant scene.
