Aspherical lenses, which have a surface of revolution of curves of the second order, show smaller aberration than spherical lens, since their eccentricity e can be varied depending on the refractive index n of materials. The focal lengthes were evaluated on these lenses having surfaces of revolution of ellipsoid, paraboloid, and hyperboloid. The lenses with revolutional surfaces of hyperboloid of two sheets (e = n) and ellipsoid (e = 1/n) have null abberation. The method of cutting both hyperboloidal and spherical surfaces is also described.
