摘要： An imaging lens includes a first lens group; a second lens group having positive refractive power; and a third lens group, arranged in this order from an object side to an image plane side. The first lens group includes a first lens having positive refractive power, a second lens, and a third lens. The second lens group includes a fourth lens and a fifth lens. The third lens group includes a sixth lens having negative refractive power and a seventh lens having negative refractive power. Each of the first lens and the second lens is formed in a shape so that a surface thereof on the object side has a positive curvature radius. The seventh lens is formed in a shape so that a surface thereof on the object side has a negative curvature radius, and has a specific Abbe's number.

摘要： An imaging lens includes a first lens having positive refractive power; a second lens; a third lens; a fourth lens; a fifth lens; and a sixth lens, arranged in this order from an object side to an image plane side. The fourth lens is formed in a shape so that a surface thereof on the image plane side is convex on an optical axis thereof. The sixth lens is formed in a shape so that a surface thereof on the image plane side is concave toward the image plane side near an optical axis thereof. The fifth lens has a specific Abbe's number and the third lens has a specific focal length.

摘要： An imaging lens includes a first lens group and a second lens group, arranged from an object side to an image plane side. The first lens group includes a first lens having positive refractive power, a second lens having positive refractive power, and a third lens having at least one aspheric surface, arranged with a space in between. The second lens group includes a fourth lens having positive refractive power and at least one aspheric surface, a fifth lens having two aspheric surfaces, and a sixth lens having two aspheric surfaces, arranged with a space in between. The fifth lens is formed in a shape so that a curvature radius of the surface on the image plane side is positive near an optical axis. The sixth lens is formed in a shape so that a curvature radius of the surface on the object side is negative near an optical axis.
