1. A spectrophotometer comprising:
a sample placement unit in which a sample to be analyzed is placed;
a light source unit that includes a plurality of light sources, each of which irradiates a sample placed in the sample placement unit with light;
a detection unit configured to detect light from the sample;
a housing configured to accommodate the sample placement unit, the light source unit, and the detection unit;
a storage unit which stores, for each of a plurality of different combinations of one or more of the plurality of light sources including at least a designated combination defined as including two or more light sources, information of a corresponding temperature value predetermined for a corresponding combination of the one or more of the plurality of light sources;
a light source designation accepting unit configured to accept the designated combination to be turned on from the plurality of light sources;
a target temperature setting unit configured to read a temperature value corresponding to the designated combination and set the temperature value to a target temperature; and
a temperature adjusting unit configured to maintain a temperature inside the housing at the target temperature, wherein the target temperature is associated with the designated combination.
