Stand Alone TCSPC Module with USB 2.0 Interface PicoHarp 300 

Measurement Examples


Coumarin 6 in Ethanol

  • Time-resolved fluorescence lifetime measurement of Coumarin 6 in Ethanol using the FluoTime 200 and a MCP-PMT.
  • Excitation with LDH-P-C-405 picosecond diode laser, 50 ps FWHM at 10 MHz repetition rate.
  • The plot shows the measured Instrument Response Function (red), the sample decay (blue) and the fitted decay. The fluorescence lifetime is 2.54 ns. An excellent chi-square of 1.001 and the residual trace demonstrate the quality of the fit. 



POPOP in Ethanol

  • Time-resolved fluorescence lifetime measurement of POPOP in Ethanol using the FluoTime 200 and a MCP-PMT module.
  • Excitation at 375 nm with LDH-P-C-375 picosecond diode laser, 70 ps FWHM at 10 MHz repetition rate.
  • The plot shows the measured Instrument Response Function (red), the sample decay (blue) and the fitted decay. The fluorescence lifetime is 1.29 ns. An excellent chi-square of 0.95 and the residual trace demonstrate the quality of the fit.
