Abstract: A V-block refractometer capable of enhancing measurement accuracy is provided. An incident angle of measurement light incident on a V-block prism 1 from a collimator lens 48 is changed through the rotation of a motor 7, and the measurement light from the V-block prism 1 at each incident angle is detected by a detector 2. This configuration eliminates the need to provide the detector 2 near the motor 7 as in the conventional art, whereby deterioration in measurement accuracy caused by an increase in load to the motor 7 can be prevented, and the measurement accuracy can be enhanced.
