Timegate PicoRaman M3

Fluorescence emission is seen as the main challenge for achieving detailed Raman analysis data.

The PicoRaman M3 spectrometer broadens the application areas of Raman spectroscopy by drastically reducing fluorescence interference. The patented, new Timegated® technology is developed to solve this issue; it is the only commercial Raman spectrometer capable of time-resolved measurements.

The PicoRaman M3 is Timegate’s 3rd generation instrument. This compact, user-friendly instrument fits on a laboratory table, and is easy to transport to a sample collection site. The instrument allows easy and autoclavable integration with process environment and is free from sample preparation—resulting in rapid set-up time. In addition, the PicoRaman M3 delivers measurements about 10 to 40 times faster than previous instrument generations.

Timegate also provides the ProbePro product family, a variety of different probe optics for in situ real-time analysis.

PicoRaman M3 provides data on Raman scattering, and also delivers time-resolved information on fluorescence emission decay.


The Achilles’ heel of conventional Raman technology is photoluminescence (including fluorescence and phosphorescence) interference. Photoluminescence is a competing phenomenon with Raman scattering and it can overlap or “swamp” Raman signals making the identification and quantification of materials impossible. With the new Timegated® technology, we can now achieve real fluorescence suppression and redefine the ways Raman spectroscopy is exploited.

Timegated® Raman technology offers several advantages over conventional Raman spectrometers and opens up enormous potential for its use in different application areas.

Key advantages:

  • Real fluorescence suppression
  • Time-resolved fluorescence information
  • Effective removal of ambient light and thermal emission interference

Timegate Instruments’ patented breakthrough innovation is an affordable electrical gating solution using pulsed picosecond range lasers and new CMOS-SPAD (Single Photon Avalanche Diode) array detectors.

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.
