Optical Unit
All the elements of the optical system, shown in Figure 7 on page 20, including
Xenon flash lamp, excitation condenser lens, excitation slit, mirror, excitation
grating, flow cell, emission condenser lens, 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.
