We have analyzed the effects of polarizer and analyzer imperfections in a phase-modulated magneto-optical Kerr spectrometer, using Jones matrices, and found that these imperfections do not seriously affect measurements of magneto-optical effects, to a first-order approximation. The analysis was experimentally proved in a magneto-optical Kerr spectrometer with a dichroic polarizer and analyzer with an extinction ratio of ∼10<sup>−2</sup>.
