2.3.4 Principle of operation
Fig. 2-11 Functional Block Diagram
The beam from the xenon lamp strikes the excitation
monochromator that disperses the radiation. Only radiation of
the specified wavelength is allowed to pass through the exit slit.
After the exit slit, the excitation radiation strikes the sample.
The fluorescence (emitted radiation) enters the emission
monochromator, where it is dispersed by the monochromator.
The selected radiation strikes the measuring detector.
On the other hand, the excitation beam which passed through
the sample enters the monitor detector via the diffusion plate.
