FPB fluorescence probes
FPB Series Fibre-Coupled Fluorescence Probes, 405–980 nm
The same solidified probe bodies as the Raman range, with the filter set chosen for fluorescence: the laser line is blocked and the emission band passed to the spectrometer. Nine excitation wavelengths from 405 to 980 nm, the last two covering up-conversion emission from rare-earth phosphors.
