Paper Abstract

Hamilton's method of characteristic functions can be used to calculate the effects of small system perturbations on image formation. In this paper we apply perturbation theory to the calculation of centering tolerances. We show how the aberrations caused by component shifts and tilts can be expressed as sums over surface contributions. We made up a computer program (called NODES) to calculate Eikonal coefficients of optical systems. With this program lens design can be optimized with regard to specific aberrations. Decentering aberrations can be included in the merit function. We give a few examples of optimization including centering tolerances.
