Abstract:
1. An image 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; a second lens element having positive refractive power; a third lens element having refractive power; a fourth lens element having refractive power; a fifth lens element with negative refractive power having a concave object-side surface, wherein both of the object-side surface and an image-side surface of the fifth lens element are aspheric; and a sixth lens element with refractive power having a concave image-side surface, wherein the image-side surface of the sixth lens element has at least one inflection point, and both of an object-side surface and the image-side surface of the sixth lens element are aspheric; wherein the image lens assembly has a total of six lens elements with refractive power, a focal length of the image lens assembly is f, a focal length of the first lens element is f1, a focal length of the second lens element is f2, an axial distance between the object-side surface of the first lens element and the image-side surface of the sixth lens element is Td, a central thickness of the sixth lens element is CT6, and the following conditions are satisfied:
