Abstract:
1. An imaging lens for a solid-state image sensor in which elements are arranged in order from an object side to an image side, comprising: a first lens as a double-sided aspheric lens with positive refractive power having convex surfaces on the object side and the image side near an optical axis; an aperture stop; a second lens with positive refractive power having convex surfaces on the object side and the image side near the optical axis; a third lens as a meniscus lens with negative refractive power having a concave surface on the image side; a fourth lens with positive refractive power having a convex surface on the image side; and a fifth lens as a meniscus lens with negative refractive power having a concave surface on the image side near the optical axis, wherein an angle of view is substantially 90 degrees, and wherein a conditional expression (1) below is satisfied: where f: focal length of an overall optical system of the imaging lens, and ih: maximum image height.
