A V-block refractometer capable of enhancing measurement accuracy is provided. The angle of incidence of measurement light that is from a collimator lens (48) and is incident on a V-block prism (1) is changed through the rotation of a motor (7), and at each angle of incidence, the measurement light from the V-block prism (1) is detected by a detector (2). As a result, it is not necessary to dispose the detector (2) near the motor (7) as in conventional refractometers, degradation of measurement accuracy resulting from increased load, and the like, on the motor (7) is prevented, and it is possible to enhance measurement accuracy. |
