| titleOfInvention | Imaging lens |
| abstract | A pickup lens is provided with various aberrations corrected satisfactorily, with a short optical length, and with a sufficient back focus secured. n The configuration comprises an aperture diaphragm S1, first lens L1, second lens L2, and third lens L3, and is configured by arranging, in order from the object side to the image side, the aperture diaphragm, first lens, second lens, and third lens. The first lens is a lens having positive refractive power, with convex surfaces on the object side and on the image side. The second lens is a lens having negative refractive power, in a meniscus shape with the convex surface on the image side. The third lens is a lens having negative refractive power, in a meniscus shape with the convex surface on the object side. Both of the surfaces of the first lens are aspherical, both of the surfaces of the second lens are aspherical, and both of the surfaces of the third lens are aspherical. |
