title: Effect of polarization on reflectance factor measurements.
abstract: Data are presented to show the effect of polarization of the incident beam on the reflectance factors of a number of reflecting materials in the visible spectrum. Data on the degree of polarization in the reflected radiation are also given. The significance of these data in colorimetry is discussed, and it is shown that serious errors may sometimes occur because of polarization in color-measuring instruments.
