title: Schmidt camera correctors for large telescopes.
abstract: Designing large Schmidt cameras using the polynomial expansion may yield a not-perfect spherical aberration correction. We indicate an alternative method to design the corrector, whose integration in a software package is in progress. The shape of the corrector can be determined with a simple recursive method. The incidence point can also be calculated for any ray, as well as the corresponding unitary vector normal to the surface.
