The optical trains of interferometers invariably contain oblique reflections that alter the polarization state of the light from the source. Even for arrays with symmetric optical paths, large systematic visibility errors can be introduced when observing sources with intrinsic polarization. We have identified the key metric for polarization fidelity in an optical interferometer - the diattenuation of the optical train - and we evaluate the visibility penalties incurred by an interferometer that is not optimized for polarimetric purity for a number of different types of polarized source.
