Patent ID: 8773773

Claim:
An imaging lens, comprising in an ordered way from an object side: a first lens having a positive (+) refractive power and being a meniscus shape convexly formed at an object side surface, wherein both surfaces of the first lens are aspheric surfaces; a second lens having a negative (−) refractive power and being a meniscus shape concavely formed at an object side surface, wherein both surfaces of the second lens are aspheric surfaces; and a third lens having a positive (+) refractive power and being an aspheric shape in which an object side surface and an image side surface both have inflection points, wherein the third lens has a meniscus shape convexly formed at an object side surface at an optical axis of the imaging lens, wherein an aperture is placed between the first lens and the second lens, wherein an image side surface of the third lens is bent to an imaging side as heading from a central part which is centered on the optical axis to a surrounding part that is farther away from the optical axis than the central part is, and forms an aspheric inflection point by bending toward an object side as heading from the surrounding part to an outermost part that is farther away from the optical axis than the surrounding part is, and wherein the imaging lens satisfies a condition of 2<f3/f<3, when an entire focal length of the imaging lens is f and a focal length of the third lens is f3.
