Scientific paper

An optical design computer program has been developed. Principally it makes the use of the method defined by D. C. Dilworth as 'pseudo-second-derivative,' which is an extension of the well-known damped least squares method. In the following exposition of the program a special procedure for the selection of the damping factor, which significantly improves the convergence of the method, is emphasized. In addition some sample problems are illustrated.
