7 Introduction to the Fluorescence Detector
The radiation emitted by the lamp is dispersed and reflected by the excitation
monochromator grating onto the cell entrance slit.
The holographic concave grating is the main part of the monochromator,
dispersing and reflecting the incident light. The surface contains many minute
grooves, 1200 of them per millimeter. The grating carries a blaze to show
improved performance in the visible range.
