Claim:
A compact imaging lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface and a convex image-side surface, at least one of the object-side and image-side surfaces thereof being aspheric; a second lens element with negative refractive power having a concave object-side surface and a concave image-side surface, at least one of the object-side and image-side surfaces thereof being aspheric; and wherein the compact imaging lens assembly further comprises an aperture stop and an electronic sensor, the aperture stop is disposed between an imaged object and the second lens element, and the electronic sensor is disposed at an image plane; wherein there are only two lens elements with refractive power in the compact imaging lens assembly, a distance on the optical axis between the first and second lens elements is T 12 , a focal length of the compact imaging lens assembly is f, a distance on the optical axis between the aperture stop and the electronic sensor is SL, a distance on the optical axis between the object-side surface of the first lens element and the electronic sensor is TTL, an Abbe number of the first lens element is V 1 , an Abbe number of the second lens element is V 2 , a radius of curvature on the object-side surface of the first lens element is R 1 , a radius of curvature on the image-side surface of the first lens element is R 2 , and they satisfy the relations: 1<( T 12 /f )*100<25; 0.5 <SL/TTL <1.3; 15< V 1 −V 2<48; −1.0 <R 2 /R 1<0.0.
