    摘要: An imaging lens includes a first lens having positive refractive power; a second lens having negative refractive power; a third lens having negative refractive power; and a fourth lens having negative refractive power, arranged from an object side to an image plane side. In the first lens, a curvature radius on an object-side surface is positive and a curvature radius of an image-side surface is negative. In the third lens, curvature radii of an object-side surface and an image-side surface are both negative. In the fourth lens, curvature radii of an object-side surface and an image-side surface thereof are both positive. When the whole lens system has a focal length f and a distance from the object-side surface of the first lens to an image-side surface of the fourth lens is L14, the imaging lens satisfies the following expression: 0.5

    摘要: An imaging lens includes a first lens having positive curvature radii on both an object side and an image side, a second lens having a concave shape on both sides, and a third lens having positive curvature radii on both the object side and the image side. The first to third lenses are arranged in this order from the object side toward the image side. When a whole lens system has a focal length f, the first lens has a focal length f1, the second lens has a focal length f2, and the third lens has a focal length f3, the following conditional expressions are satisfied: f1

    摘要: A laminated optical element includes an optical substrate made of an optical material, an intermediate layer provided on the optical substrate, and an optical resin layer provided on the intermediate layer. The optical resin layer is made of a resin composed of an organometallic polymer having an -M-O-M- bond (M is a metal atom), a metal alkoxide and/or a hydrolysate thereof having only one hydrolyzable group, and an organic polymer having a urethane bond and a methacryloxy group or an acryloxy group. The intermediate layer is obtained by dispersing metal oxide microparticles in a matrix resin composed of a metal alkoxide having a radical polymerizable group and a hydrolyzable group and/or a hydrolysate thereof.
