Patent ID: 8743483

Claim:
An imaging lens assembly comprising, in order from an object side to an image side: a first lens element with negative refractive power having a convex object-side surface and a concave image-side surface; a second lens element with positive refractive power; a third lens element with refractive power; a fourth lens element with refractive power, wherein an object-side surface and an image-side surface of the fourth lens element are aspheric; a fifth lens element with positive refractive power, wherein an object-side surface and an image-side surface of the fifth lens element are aspheric; and a sixth lens element with negative refractive power having a concave image-side surface, wherein the sixth lens element has at least one inflection point on the image-side surface thereof; wherein a curvature radius of an object-side surface of the sixth lens element is R 11 , a curvature radius of the image-side surface of the sixth lens element is R 12 , a focal length of the imaging lens assembly is f, a focal length of the sixth lens element is f 6 , and the following relationships are satisfied: 0 <|R 12 /R 11|<1.0; and −2.5 <f/f 6<−0.60.
