Abstract: An imaging lens assembly includes, in order from an object side to an image side, a first lens element with positive refractive power, a second lens element with negative refractive power, a third lens element with positive refractive power. The first lens element has a convex image-side surface in a paraxial region. The second lens element has a concave object-side surface and a convex image-side surface in a paraxial region, and at least one of its surfaces is aspheric. The object-side surface of the third lens element is convex in a paraxial region and concave in a peripheral region. The image-side surface of the third lens element is concave in a paraxial region. The object-side surface and image-side surface of the third lens element are both aspheric. The imaging lens assembly satisfies 0.062 mm<D<0.091 mm, where D represents the maximum effective focus shifts range under all the defocus curves at 0.4 modulus of the OTF (optical transfer function).

Abstract: An optical imaging module used in portable devices is described. In order from an object side to an image side, the module comprises an aperture stop, a first lens element with positive refractive power having a convex object-side surface and a convex image-side surface; a second lens element with negative refractive power having a concave image-side surface and a object-side surface being convex in a peripheral region; a third lens element with refractive power; a fourth lens element with refractive power having a convex image-side surface; a fifth lens element with positive refractive power having an image-side surface being concave in a paraxial region and convex in a peripheral region; and wherein the optical imaging module used in the portable devices satisfies: 0.052 mm?D?0.082 mm, where D represents a maximum effective focus shifts range under all the defocus curves at 0.4 modulus of the OTF (optical transfer function).
