Horiba Jobin-Yvon TCSPC on the FluoroLog-3

TCSPC on the FluoroLog®-3

TCSPC on the FluoroLog®-3 With Time Correlated Single Photon Counting (TCSPC) accessories, the FluoroLog®-3 is also a complete, stand-alone steady-state and lifetime spectrofluorometer using the outstanding sensitivity of photon counting in the time domain.


Time Correlated Single Photon Counting on the World's Most Sensitive Spectrofluorometer

We start with the best steady-state optical bench from HORIBA Jobin Yvon SPEX®, add in a pulsed laser-diode or a pulsed spark source, and finish with a superior detector-module.

The Result?

The World's Most Sensitive Spectrofluorometer, with TCSPC ready to perform time-domain lifetime spectroscopy! You get the reliability and know-how of the SPEX® FluoroLog® series, together with the solid-state economy and sensitivity of IBH lifetime analysis, all in one instrument. All functions are software controlled from a host computer, giving you access to data with just a few keystrokes. A high repetition rate light source rapidly builds up a histogram of the sample's fluorescence decay.

So why use TCSPC for time-resolved experiments?

  • Variations of the excitation beam's intensity are irrelevant
  • Detects individual photons
  • No pulse-smearing from boxcar gates
  • High speed data-acquisitions
  • Digial precision, and no analog offset required for fitting results
  • The entire decay curve is examined at once

Of all the modern time-domain methods, including boxcar integration and streak cameras, TCSPC has by far the best dynamic range. If your sample lifetimes are really important, then SPEX®-IBH TCSPC is the method for you.
