F200
For absorbance measurements a similar optical path is used as for fluorescence
excitation. The absorbance measurement module is located underneath the plate
carrier. It measures the light being transmitted through the sample. Before
measurement of the microplate, a reference measurement is performed with the
plate carrier moved out of the light beam (see also 2.2.2 Absorbance).
