Fluorolog TCSPC Spectrofluorometer from HORIBA

The Fluorolog TCSPC Spectrofluorometer, available from HORIBA Scientific, is touted to be the most sensitive tool in the world and is ideal for time correlated single photon counting. Featuring HORIBA Jobin Yvon SPEX’s steady-state optical bench, a pulsed spark source or pulsed laser-diode, and an advanced detector-module, the Fluorolog TCSPC spectrofluorometer is apt for performing time-domain lifetime spectroscopy.

Users get the reliability and expertise of the SPEX Fluorolog series combined with sensitivity and solid-state economy of lifetime analysis in a single system. The entire functions are controlled using software from a host computer and access to data is provided simply at the touch of the keys. A light source of high repetition rate instantly creates a histogram of the sample’s fluorescence decay.

Key Features

Product features of the Fluorolog TCSPC Spectrofluorometer are:

  • Detects individual photons
  • High speed data-acquisitions
  • No pulse-smearing from boxcar gates
  • Changes in the excitation beam's intensity are immaterial
  • Digital accuracy
  • Analog offset is not needed for fitting results
  • The full decay curve is analyzed instantly

The The Fluorolog TCSPC Spectrofluorometer provides an exceptional dynamic range, when compared to other time-domain techniques, which comprise boxcar integration and streak cameras. To ensure sample lifetimes, the SPEX-IBH TCSPC provides an ultimate solution.
