Abstract. The possibility is considered of correction of spherical aberration of a single lens by introduction of axial, radial, and spherically concentric inhomogeneity of refractive index. Comparison with results obtained with aspherization of second-order surface is carried out.
Keywords: spherical aberration, aspherical surface, radial (axial, spherically concentric) refractive index imhomogeneity.
