High Performance Fluorescence Lifetime and Steady State Spectrometer



The FluoTime 300 "EasyTau" is a fully automated, high performance fluorescence spectrometer for steady-state, life time and phosphorescence measurements. The FluoTime 300 contains the complete optics and electronics for recording steady state spectra and fluorescence decays by means of Time-Correlated Single Photon Counting (TCSPC) or Multichannel Scaling (MCS) from few picoseconds to several seconds. The system is designed to be used with picosecond pulsed diode lasers, LEDs or Xenon lamps (CW and pulsed). Multiple detector options enable a large range of system configurations from the UV up to the IR range. The system features an ultimate sensitivity with 29000:1 Water Raman SNR. The FluoTime 300 can be used to study fluorescence and phosphorescence decays from few picoseconds to several seconds. With a large range of additional accessories the system is an excellent standard for research and analysis.
