The grating in a monochromator introduces some polarization into the optical beam, the amount depending on the geometry of the system and on the type of grating. A knowledge of this polarization is important, whether the monochromator is used for the spectral analysis of an experimental source of electromagnetic radiation or to produce monochromatic radiation for optical or photoelectric yield experiments. Since it cannot, at this time, be calculated theoretically it is necessary to measure directly the polarization introduced by the grating. The polarization introduced by various gratings used in the Seya-Namioka geometry was previously measured. These observations are extended to a grazing-incidence geometry which is employed in grazing-incidence monochromators to obtain spectra to smaller wavelengths than is possible with a Seya-Namioka monochromator.
