Abstract
A device includes a sample chamber (1) configured to receive the object, a polarization degree measuring member (2) configured to measure the polarization degree of the object received in the sample chamber (1), and a refractive index measuring member (3) configured to measure information corresponding to the refractive index of the object received in the sample chamber (1). The polarization degree measuring member (2) includes a polarization modulation member (11) configured to perform polarization modulation on a light beam (9) for analyzing the object and allow the modulated light beam to enter the sample chamber (1), an intensity detection member (12) configured to detect an intensity of the light beam (5) exiting from the sample chamber, and a polarization degree calculation member (13). The refractive index measuring member (3) includes a position detection member (26) and a refractive index (concentration) calculation member (13).
