Evolution of the transverse response of an optical system with complex filters

In many optical systems a specific axial behaviour is needed. It is very common to search for high focal depth and an almost constant distribution along the axial coordinate. An additional condition to be required could be symmetrical axial response. The transverse response in the best image plane i...
