Abstract

Materials suitable for the construction of achromatic lenses corrected for four wavelengths are selected by the use of three graphs which are the three orthographic projections of a three-dimensional graph in P, Q, and V; where V=(n_d−1)/(n_F−n_C), P=(n_h−n_C)/(n_F−n_C), and Q=(n_1.014−n_C)/(n_F−n_C). One set of three glasses, Schott PKS-1, F-1, and KzFS-4, has been selected, from which a four-color achromat has been designed. Analysis at 12 wavelengths shows this design to have negligible residual chromatic aberration. It is consequently a superchromat in accordance with Herzberger’s prediction.
