FL920 Spectrometer - System Flexibility

There are a number of off the shelf upgrade routes for the FL920. For example, the FL920 can be easily upgraded to measure phosphorescence lifetimes spanning the range from 1microseconds to 10 seconds by incorporating a low repetition rate excitation source, our PCS900 card and using the Multi-Channel Scaling acquisition mode of this card. This instrument is our FL920P. The FL920 can also be upgraded to measure steady state luminescence spectra by the addition of a CW Xenon lamp and our PCS900 card used as a fast pulsed scalar counter card. This combined fluorescence lifetime and steady state instrument the FLS920 is a complete laboratory in one instrument.

Below you will find a table detailing some of the more common upgrade routes for the FL920. If you do not see your exact requirements listed, please contact the factory.
