In the channeled spectroscopic polarimetry, a measurement error of a parameter showing a spectropolarization characteristic of a sample is effectively removed, the error being generated by various variations in retardation of a retarder depending upon the state of the sample. With attention being focused on that the retardation of the retarder may be kept constant by stabilization of an incident direction of light that transmits through the retarder, the retarder was arranged on the light source side with respect to the sample so as to effectively remove an influence relative to a measurement error, such as variations in direction of a light ray due to the sample.
