title: Optical aberration functions: derivatives with respect to axial distances for symmetrical systems.
abstract: Simplified formulas are presented for the computation of derivatives of the optical aberration functions S,T,V,W, and K with respect to the axial surface distances for symmetrical optical systems. The formulas are well-suited for implementation in computer programs for automatic computation of optical aberration coefficients.
