Previous investigations involving the design of gradient lenses have been based mostly on third-order aberrations. The present paper discusses design techniques based on total aberrations. In particular, an algebraic formula is found for the total meridional curvature of radial gradient singlets. The formula obtained holds for a large class of refractive-index profiles.
