Abstract:
1. An imaging lens in which elements are arranged in order from an object side to an image side, comprising: a first lens with positive refractive power having a convex surface on the object side near an optical axis; a second lens with negative refractive power having a concave surface on the image side near the optical axis; a third lens with positive refractive power having a convex surface on the image side near the optical axis; a fourth lens with negative refractive power having a concave surface on the image side near the optical axis; a fifth lens with positive refractive power as a meniscus lens having a convex surface on the image side near the optical axis; a sixth lens as a meniscus double-sided aspheric lens having a concave surface on the image side near the optical axis; and a seventh lens with negative refractive power as a double-sided aspheric lens having a concave surface on the image side near the optical axis.
