- Time-resolved fluorescence lifetime measurement of Coumarin 152 (3·10-7 molar) in Ethanol using the FluoTime 100, TimeHarp 200 and PMT module PMA 182.
- Excitation with LDH-P-C-405 picosecond diode laser, 50 ps FWHM at 20 MHz repetition rate.
- The plot shows the measured Instrument Response Function (red), the sample decay (blue) and the fitted decay. The fluorescence lifetime is 1.59 ns. An excellent chi-square of 0.912 and the residual trace demonstrate the quality of the fit.

- Time-resolved fluorescence lifetime measurement of Oxazin 1 (1·10-6 molar) in Water using the FluoTime 100, TimeHarp 200 and PMT module PMA 182.
- Excitation at 635 nm with LDH-P-635 picosecond diode laser, 70 ps FWHM at 20 MHz repetition rate.
- The plot shows the measured Instrument Response Function (red), the sample decay (blue) and the fitted decay. The fluorescence lifetime is 799 ps. An excellent chi-square of 1.051 and the residual trace demonstrate the quality of the fit.

- Fluorescence decay measurement of Oxazine 1 with a trace amount of Oxazine 4 (10-6 molar solution in Ethanol). Data acquired using a FluoTime 100 spectrometer, TimeHarp 200 and a LDH-P-635.
- Fluorescence with λ>670 nm was collected. The plot shows the measured Instrument Response Function (red), sample decay (blue) and the fitted double exponential curve (black). The two recovered lifetimes are 0.97 ± 0.02 ns and 3.71 ± 0.09 ns, respectively. They are in excellent agreement with the single exponential lifetimes of Oxazine 1 and Oxazine 4, respectively, determined in independent experiments. The weighted residuals' trace and chi-square = 1.158 demonstrates the quality of the fit.
