Paper Abstract

The theory explaining how third-order aberrations depend on magnification has been discussed by Wynne and Welford. In this paper we show how the `conjugate-change equations' can be used to find out under what conditions a lens can be designed, with front-back symmetry, which is well-corrected, for a range of object distances.
