Absorbance

The workhorse of the lab. Compares the light entering the sample to the light exiting the sample. Any light absorbed, scattered, or otherwise attenuated results in an increase in signal (OD).

Luminescence

Light emitted by the sample itself (e.g. due to a chemical or biochemical reaction) is collected by a sensitive detector. Total light within the range of the detector is collected and reported as Relative Light Units (RLU).

03

Fluorescence

One light in, a different light out. A dye works when it is excited inside the blue band and glows inside the green one; each line runs from a dye's excitation peak to its emission peak.
