Ultrafast, Limited Pixels Fibre Optic Spectrometer

USB UV/VIS spectrometer

For ultra-fast spectral acquisition, the AvaSpec-Fast offers the best solution.


Up to 5637 spectra can be stored at 0.20 ms per scan using Avantes unique store-to-RAM functionality. Depending on the configuration chosen, between 1254 and 5637 spectra can be stored during one burst.

The AvaSpec-FAST series is available in five different configurations - the difference being the number of active pixels. More pixels provide higher resolution or more bandwidth, but slower minimum integration time reducing speed. For all models, start/stop pixels can be set in our software to increase the number of scans stored on board over a shorter wavelength range.

The AvaSpec-FAST can be configured in CR or SS mode. CR, or continuous run, mode means a single external trigger (through the DB26-connector) results in a customer set number of scans automatically being measured. SS-mode, for single scan, means a single spectrum is acquired at every external trigger. CR or SS mode must be specified at the time of order.

Possible configurations are single or dual channel, desktop or rackmounted. The instrument is available with all the options and gratings of the AvaSpec-ULS2048.
