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