Freeform aplanatic systems (Póster)


We formulate freeform aplanatic systems as a limiting case of a 3D SMS design. We establish how two optical surfaces when considered for achieving freeform aplanatism leads to no solution and thus, prove that freeform aplanatic systems need three optical surfaces with the exception of afocal aplanatic systems. We also present basic formulations governing a three surface freeform aplanat along with few examples.
