From a set of previously derived equations for conic surfaces, we derived another set of equations from which the conic constant k and the paraxial radius of curvature r can be obtained, if at least three values of the longitudinal aberration X and their corresponding angles θ of the normals to the surface are measured. The procedure is useful when the area around the vertex surface cannot be used. Some experimental results are presented.
