Abstract
An imaging lens assembly includes, in order from an object side to an image side, a stop, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has a convex object-side surface. The second lens element with negative refractive power has a concave image-side surface. The third lens element has refractive power. The fourth lens element has refractive power. The fifth lens element has refractive power. The sixth lens element with refractive power has a concave image-side surface at a paraxial region thereof, wherein the image-side surface of the sixth lens element has a convex shape at an off-axis region, and both of the surfaces of the sixth lens element are aspheric. The imaging lens assembly has a total of six non-cemented lens elements with refractive power.
