PROBLEM TO BE SOLVED: To provide a spectrophotometer capable of further reducing the temperature change of a spectroscopic part which accommodates a spectroscopic element, a sample, and the like as compared with the conventional spectrophotometer.SOLUTION: The spectrophotometer 1 includes: a light source chamber 10; a light source chamber 20 which is separated from thee light source chamber 10 with a heat insulating part intervened and includes at least a spectroscopic element 24, a sample chamber 22, and a detector 25; temperature measuring means 40 for measuring a temperature inside the spectroscopy chamber 20; temperature adjusting means 50 for heating and/or cooling an interior of the spectroscopy chamber 20; and control means 31 for acquiring temperature information from the temperature measuring means 40 and allowing the temperature adjusting means 50 to operate so that the predetermined set temperature is maintained inside the spectroscopy chamber 20. |
