Abstract

A control unit for controlling the temperature of a spectrometer to be constant stores a first temperature coefficient indicating a proportion of a temperature change of the spectrometer to a room temperature change and a second temperature coefficient indicating a proportion of the temperature change of the spectrometer to a change in the air volume of blower means, and calculates the amount of change in the air volume of the blower means necessary to offset a change in the temperature of the spectrometer from a predetermined constant temperature, by using the first temperature coefficient and the second temperature coefficient, and controls driving of the blower means based on the calculated amount of change in the air volume.
