摘要： This invention provides a compact imaging lens assembly, in order from an object side to an image side, including a first lens element with positive refractive power having a convex object-side surface and a concave image-side surface with at least one of the two surfaces thereof being aspheric, a second lens element with negative refractive power having a concave object-side surface and a convex image-side surface with at least one of the two surfaces thereof being aspheric, and an aperture stop disposed between the first and second lens elements. There are only two lens elements with refractive power in the compact imaging lens assembly. By such an arrangement, total track length and optical sensitivity of the compact imaging lens assembly can be reduced while a high image quality can also be obtained.
