Abstract:
A compact low-cost imaging lens which provides brightness with an F-value of 2.5 or less and a wide field of view and corrects aberrations properly, meeting the demand for low-profileness. The imaging lens elements are arranged in the following order from an object side to an image side: a first lens with positive refractive power having a convex surface on the object side; a second lens with negative refractive power; a third lens with positive or negative refractive power having at least one aspheric surface; a fourth lens with positive refractive power; a fifth lens as a meniscus double-sided aspheric lens having a concave surface near an optical axis on the image side; and a sixth lens as a meniscus lens having a concave surface near the optical axis on the object side. The both surfaces of the fifth lens have pole-change points off the optical axis.

Claim (Index 34):
The imaging lens according to  claim 25 , wherein conditional expressions (9) and (10) below are satisfied:\n 1.0<( r 9+ r 10)/( r 9\u2212 r 10)<2.7\u2003\u2003(9) \u22121.5<( r 11+ r 12)/( r 11\u2212 r 12)<\u22120.5\u2003\u2003(10) where r9: curvature radius of an object-side surface of the fifth lens, r10: curvature radius of an image-side surface of the fifth lens, r11: curvature radius of the object-side surface of the sixth lens, and r12: curvature radius of an image-side surface of the sixth lens.
