Abstract:
This present disclosure provides an image lens assembly in order from an object side to an image side comprising five lens elements with refractive power: a first lens element with negative refractive power having a concave image-side surface; a second lens element with positive refractive power having a convex image-side surface; a third lens element with positive refractive power having a concave object-side surface and a convex image-side surface; a fourth lens element with negative refractive power; and a fifth lens element with positive refractive power. By such arrangement, sufficient field of view is provided, and the aberration of the lens assembly is corrected for obtaining higher image resolution.
