4. Define cooling temperature of the CCD-matrix (in the range of –40÷–50 °C) in the
input field available in the Toolbar (Fig. 9-5).

5. Start cooling the CCD-matrix by pressing the
of the input field. The cooling process will begin and the text caption of the pressed-in
button will indicate the current temperature of the matrix.
6. Adjust parameters controlling spectrum detection by the CCD-camera through the
following steps:
a. Enter the exposure time in the range of 0.2÷1 s in the
b. Define the highest rate for spectra detection by selecting
group of the Instruments parameters adjustment panel (Fig. 9-4).
