Abstract

The present disclosure discloses an imaging lens assembly. The imaging lens assembly includes, sequentially from an object side to an image side of the imaging lens assembly, a first lens having a positive refractive power and a convex object-side surface; a second lens having a negative refractive power and a concave image-side surface; and at least one subsequent lens. At least one of the first lens, the second lens, or the at least one subsequent lens is a glass aspheric lens. A transmittance T1 of the imaging lens assembly corresponding to a wave band 650 nm satisfies: T1>85%, a transmittance T2 of the imaging lens assembly corresponding to a wave band 490 nm satisfies: T2>88%, and a transmittance T3 of the imaging lens assembly corresponding to a wave band 430 nm satisfies: T3>75%.
