title: Optical aberration functions: chromatic aberrations and derivatives with respect to refractive indices for symmetrical systems.
abstract: Formulas are presented for the computation of derivatives of the optical aberration functions S, T, V, W, and K with respect to the relative refractive indices, leading to the chromatic aberrations, for symmetrical optical systems. The formulas are suitable for use in computer programs for automatic computation of optical aberration coefficients.
