A shutter is placed at the monochromator exit port to block the light from the detectors. A baffle is placed in front of the detectors to block stray light. A beam splitter is positioned in the beam in front of the baffle to direct light to a monitor detector. A laser can also be selected as a source for alignment of the detectors. C.
