Expressions are available for the polynomial coefficients of a doublet in terms of those of the individual members of the doublet for both geometrical and chromatic aberrations. Here, these expressions are used to search for favorable lens doublet configurations when the chromatic aberration is the most important Workplace Institute of Scientific Instruments Contact Martina Šillerová, sillerova@ISIBrno.Cz, Tel.: 541 514 178 Year of Publishing 2008
