ABSTRACT:
A double-beam spectrophotometer of the invention is provided with a sector mirror used at a luminous flux separating portion or at a luminous flux combining portion, and a DC brushless motor is used for actuating the sector mirror to rotate. Since the DC brushless motor is used, the sector mirror can be rotated at high speed with few noise. Also, the double-beam spectrophotometer can measure the change in the short period of time.
