FluoMax Fluorescence Up-conversion Kinetic Spectrometer


Fluorescence Up-conversion Kinetic Spectrometer

FluoMax is a turn-key system for investigation of fluorescence kinetics in solutions, solid samples and thin films. It has a time window of up to 4 ns with sub-100 fs intrinsic time resolution. The detection method relies on sum-frequency generation in optical nonlinear crystal using femtosecond optical gating. The spectral range of FluoMax covers the near-UV, visible and the NIR-infrared regions. It has been designed to be matched with any type of femtosecond titanium-sapphire (at 680-1040nm) or itterbium (at 1030-1060nm) oscillators (1-100 MHz, SC version) and the Ti-Sa or Yb regenerative amplifiers (0.1-10 kHz, MP version).
