The classical prescription for accurate optical and IR polarimetry is the following: a weakly polarizing telescope, a polarization modulator, imager/disperser optics, and a demodulating detector. This list needs to be modified when one is forced to use the Nasmyth focus, as often happens in large modern facilities. An ex- tension of the basic paradigm is presented here and worked out in some detail.
