The properties of the Y−Ӯ diagram as applied to radial gradient lens systems are developed. It is shown that the diagram consists of elliptical arcs, which are circular arcs for certain conditions. The effects of pupil and object shifts are discussed as well as the effects of scaling the pupil size. It is shown how the constructional parameters of the system are read from the diagram. Finally, for the purpose of design, it is shown how one may obtain the Y−Ӯ diagram of a system which satisfies a certain set of design constraints.
