Abstract : A computer program has been written that outputs one of several sets of optical system parameters, while iterating one of the input parameters. The code can handle a system of one to three optical elements; these can be refracting or reflecting surfaces, or thin lenses. Output is available in tabular numerical form, as a graph, or both. Current subroutines provide: the system AFCD matrix and cardinal points; the location and magnification of the final image of the system; the separation of the elements needed to obtain a specific magnification and position of the final image; the powers of two of the elements required to obtain a specific magnification and position; and the power and position, of one of the elements, needed to obtain a specific magnification and position.
