Abstract:
An imaging lens includes a first lens having positive refractive power; a second lens having positive refractive power; 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 with spaces in between each of the lenses. The first lens is formed in a meniscus shape to have an object side convex surface. The sixth lens is formed in a meniscus shape to have an object side concave surface. The second lens has a specific focal length. The third lens has a specific focal length. The sixth lens has a specific Abbe's number.
