| titleOfInvention | Imaging lens |
| abstract | Various aberrations are satisfactorily corrected, the optical length is short, and sufficient back focus is ensured. An aperture stop S1, a first lens L1, a second lens L2, and a third lens L3 are provided. The aperture stop, the first lens, the second lens, and the third lens are arranged in this order from the object side to the image side. Arranged and configured. The first lens is a lens having a positive refractive power with convex surfaces facing the object side and the image side. The second lens is a meniscus lens having a negative refractive power with a convex surface facing the image side. The third lens is a meniscus lens having negative refractive power and having a convex surface facing the object side. Further, both surfaces of the first lens are aspheric surfaces, both surfaces of the second lens are aspheric surfaces, and both surfaces of the third lens are aspheric surfaces.
