SPECTROMETER CONTROL PARAMETERS
For spectometer control are used next parameter groups.

  • Chanels and Smoothing - this options allows to switch on/off every optical chanel (Master, Slave1, Slave2, Slave3) and set smothing parameter in range from 0 to 7 separatedly for each chanel.

  • Scan parametrs:
    • integration time- this option changes the CCD readout frequency and therefore the integration time of the CCD detector (from 2 to 60000 msec);
    • average - number of scans to avarage;
    • saturation detection level .
  • Correct for Dynamic Dark - includes 2 parameters:
    • switch on/off correction procedure;
    • forget percentage - percentage of the new dark value pixels that has to be used (from 0% to 100%).
