Analysis of a particular interferometer shows that severe polarization effects in interferograms of conical optical elements can be prevented. A simple formula is derived for correcting residual polarization effects due to spatially varying reflection coefficients. The formula can be used for estimating whether a correction is required. Several applications are discussed.
