Features
- Femtosecond-to-microsecond measurements
- Automated switching between fluorescence upconversion and TCSPC
- Automated spectral scanning and calibration
The HARPIA-TF is a time-resolved fluorescence measurement module that combines fluorescence upconversion and TCSPC techniques. In fluorescence upconversion, the signal from the sample is mixed in a nonlinear crystal with a gating femtosecond pulse to achieve high temporal resolution, which is limited by the duration of the gate and pump pulses. For fluorescence decay times in the nanosecond to microsecond range, the instrument can be used in time-correlated single‑photon counting (TCSPC) mode to measure kinetic traces up to 5 μs. The combination of the two methods enables the measurement of spectrally-resolved fluorescence decay in the femtosecond to microsecond range. Using a high repetition rate PHAROS or CARBIDE laser, the fluorescence dynamics can be measured while exciting the samples with pulse energies down to several nanojoules.
- Spectral range is extendable to NIR; contact sales@lighton.com for details.
- High-speed detector available (< 50 ps); contact sales@lighton.com for details.
- Maximum measurement range depends on the phosphorescence signal.
