An aperture stop is disposed on the optical axis between the third and fourth refractive elements. The input surface of the third refractive element, the output surface of the third refractive element, the input surface of the fourth refractive element, the output surface of the fourth refractive element, of a combination of the foregoing have radial symmetry.
