发明名称 Optical imaging lens assembly
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.
