MINITAU-TCSPC
Time-Correlated Single Photon Counting for fluorescence lifetimes of ~25 ps – 10 µs
MINITAU-MCS
Multi-Channel Scaling for phosphorescence lifetimes of 10 ns – 10 s
MINITAU-DUAL
Combines TCSPC and MCS to cover the full range of ~25 ps – 10 s
The Mini-tau spectrometer can be used with Edinburgh Instruments pulsed sources for TCSPC and MCS (EPL, EPLED, HPL, VPL, VPLED). Switching between sources only takes a few seconds and does not require any alignment.
The standard cuvette holder features water/coolant circulation for adjusting temperature. An external bath (not included) is required.
This sample holder is suitable for measuring front-face emission of slides and powders in cuvettes. Two additional inserts are supplied. Insert for holding films/slides, and insert comprising demountable cuvette.
