Introduction to the Fluorescence Detector 7
1100 Series FD Reference Manual 243
Optical Unit
All the elements of the optical system, shown in Figure 77 on page 244,
including Xenon flash lamp, excitation condenser, excitation slit, mirror,
excitation grating, flow cell, emission condenser, cut-off filter, emission slit,
emission grating and photo-multiplier tube are housed in the metal casting
inside the detector compartment. The fluorescence detector has
grating/grating optics, enabling the selection of both excitation and emission
wavelengths. The flow cell can be accessed from the front of the fluorescence
detector.
