Because the echelle spectrograph described elsewhere on this site was designed to operate at visible and near-visible wavelengths, the charhe coupled device (CCD) was chosen as the most suitable type of detector for this spectrograph. With this in mind, a moderately detailed summary of the characteristics and operation of the CCD detector is presented here.
