Using a Rayleigh beacon as reference source for an adaptive optics system, the latter can be limited by the differential aberrations introduced by the telescope optics on the image of the spot, namely some spherical aberrations introduced by the different range of the beacon with respect to the science target. The introduction of new concepts about wavefront sensing along an extended range of altitudes makes urgent the solution of this problem. In this paper we analyze the possibility to provide such a correction using a simple optical device, actually a Schmidt-like plate. We demonstrate that such a solution exists, for which the residual aberration can be nulled up to the second order in the displacement from a pre-defined point along the optical axis. A couple of examples, verified by a ray-tracing analysis, are also reported.
