<p><P>PROBLEM TO BE SOLVED: To provide a spectroscopic analyzer capable of precisely measuring the quality evaluation value of a measuring target by properly controlling the temperature of a light receiving means in a non-disadvantageous state bringing about the scaling-up of the spectroscopic analyzer or an increase in cost. <P>SOLUTION: The spectroscopic analyzer is equipped with temperature detecting means 63a and 63 for detecting the temperature of the light receiving means 2 for receiving the spectrally diffracted light obtained by spectrally diffracting the transmitted light from the measuring target, temperature adjusting means 60a and 60b for adjusting the temperature of the light receiving means 2 and a temperature control means for controlling the operation of the temperature adjusting means 60a and 60b so as to hold the temperature of the light receiving means 2 to a target temperature. The temperature control means is constituted so as to be freely changed over to a high temperature side adjusting state controlling the operation of the temperature adjusting means 60a and 60b by setting a high temperature side target temperature and a low temperature side adjusting state controlling the operation of the temperature adjusting means 60a and 60b by setting a low temperature side target temperature lower than the high temperature side target temperature. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
