Fluorescence Spectroscopy
The light level from fluorescence is often at the photon counting level, requiring a photomultiplier module for light detection

Measurement of time resolution to the sub-nanosecond level is also important.
Photomultiplier modules are used as detectors in chromatography applications where fluorescence methods are used.
