Simple equations used for analyzing chromatic aberrations of Selfoc lenses were derived in terms of Buchdahl chromatic coordinates and Buchdahl dispersion constants. The equations that employ gradient-index chromatic constants Ψ(1) and Ψ(2) are used for selecting suitable ion-exchange pairs to design an achromatic Selfoc lens.
