Component Function
Lamp and lamp
optics
Focuses light from the deuterium source lamp through a
beamsplitter to the flow cell.
Beamsplitter and
reference diode
Reflects part of the light back to a reference diode, which
measures the intensity of the light emitted by the lamp. The
detector uses this measurement to keep the lamp output constant.
