Timegated® Raman technology offers several advantages over conventional Raman spectrometers and opens up enormous potential for the use of this new technology in different application areas and material classes like:
Timegated® Raman provides real fluorescence suppression capabilities. It is also much less sensitive to ambient light and thermal emission interference.
How does Time-gating work:
The picosecond range laser excitation source and a time-gated single photon counting array detector create a totally new type of spectrometer which is able to acquire Raman spectra with real fluorescence suppression. The system rejects the fluorescence interference (which has a longer average delay) while capturing the instantaneous Raman scattering signal. It also enables the acquisition of time-resolved fluorescence spectra by sequentially sampling the emission pulses at different temporal positions. This approach simultaneously opens two windows for material characterization and provides valuable new information in several different application fields.
Summary of the advantages of this fascinating new technique:
- Real fluorescence suppression
- Time-resolved fluorescence information
- Non-destructive, non-contact, label-free, fast and easy to use measurement technique
- Thermal and ambient light interference suppression
