Patent ID: 8094387

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, 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 an aperture stop disposed between the first lens element and the second lens element; wherein there are two lens elements with refractive power in the compact imaging lens assembly; and wherein the compact imaging lens assembly further provides an electronic sensor for image formation, 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, a distance on the optical axis between the image-side surface of the second lens element and the electronic sensor is Bf, a focal length of the compact imaging lens assembly is f, and they satisfy the relations: 0.58< SL/TTL< 0.88; 0.18< Bf/f< 0.60.
