发明名称 IMAGING LENS ASSEMBLY
摘要 This invention provides an imaging lens assembly including: in order from an object side toward an image side: a first lens with positive refractive power having a convex object-side surface and a convex image-side surface, a second lens with negative refractive power having at least one of its object-side surface and image-side surface being aspheric, a third lens with negative refractive power having a concave image-side surface, and both of its object-side surface and image-side surface being aspheric. An aperture stop is positioned between the first lens element and second lens element. The imaging lens assembly further comprises an electronic sensor on which an object is imaged, and there are three lens elements with refractive power.
