摘要： This invention provides a compact imaging lens assembly in order from an object side toward an image side including a first lens with positive refractive power having at least one of the object-side and image-side surfaces thereof being aspheric, a second lens with negative refractive power having a concave object-side surface and a concave image-side surface with at least one of both surfaces thereof being aspheric, and an aperture stop positioned between the first lens element and the second lens element. There are two lens elements with refractive power in the compact imaging lens assembly.

摘要： This invention provides a photographing optical 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 and a convex image-side surface; a second lens element with positive refractive power having a concave object-side surface and a convex image-side surface, both of the two surfaces being aspheric; a third lens element with negative refractive power having a concave image-side surface on which at least one inflection point is formed, both of the two surfaces being aspheric; and a stop disposed between an imaged object and the second lens element; wherein there are only three lens elements with refractive power. Such an arrangement of optical elements can effectively reduce the size of the lens assembly, mitigate the sensitivity of the optical system and enable the lens assembly to obtain a higher resolution.

摘要： This invention provides an optical imaging lens assembly comprising five lens elements with refractive power, 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 with negative refractive power; a third lens element with negative refractive power; a fourth lens element with negative refractive power having at least one of the object-side and image-side surfaces thereof being aspheric; and a fifth lens element having a concave image-side surface, at least one of the object-side and image-side surfaces thereof being aspheric, and made of plastic. By such arrangement, photosensitivity and total track length of the optical imaging lens assembly can be reduced, and the aberration and astigmatism of the assembly can be effectively corrected. Moreover, high image resolution can be obtained.
