    The Raman Rxn5 detection module is where the collected Raman scattered light from the sample is measured. There are four analysis channels in the Raman Rxn5 detection module, one for each of the four streams. The Raman scattered light from these four streams enters the detection module where it is dispersed onto four separate regions of a charge coupled device (CCD) array in a similar manner to how a prism breaks up light into separate colors.
