Ultrafast Systems offers an integrated computer controlled filter wheel, which can be equipped with various Neutral Density filters for automated data collection with different pump intensities. Automated extraction of kinetics at a particular wavelength or range of wavelengths can be performed and saved to a text file or exported directly to Origin for ease of data processing.
Other possible applications of the filter wheel accessory include incorporation of wave plates or polarizers for automatic anisotropy measurements.
Currently the software supports up to 2 filter wheels for a total of 36 filter combinations. If purchased as an upgrade to an existing system an update of the spectrometer software to the latest version is included.
