4.2.1 Combination Optics (Fluorescence Intensity and Absorbance)
The combination optic is made up of two liquid-filled light guides for
fluorescence intensity and a quartz fiber for absorbance measurement (figure
12).
To position the measurement head with the quick-fix holders, see chapter 4.2
Installation and Changing of Optics
.
For fluorescence measurements: excitation enters through the yellow marked
light guide and emission is measured through the blue marked light guide.
For absorbance measurements: The grey, red marked, absorbance light guide
excites from above and the absorbance is measured through the bottom optic.

Regarding reagent injection: be careful when you position the needles in the measurement head (see figure
13) to avoid damage to the reagent needles as well as to the optic. The optional reagent injectors need to be
available.
