Edinburgh FLS1000 Spectrometer and Lifetime Measurement

The Edinburgh FLS1000 Spectrometer can be used for near-IR to near-UV fluorescence spectroscopy. Using a white light source, spectrographic measurements can be made by sweeping the excitation monochromator, exit monochromator, or both in a 2D spectrum map. Using pulsed sources (laser diode or LED) electronically synchronized with the detector, fixed wavelength lifetime measurements can be made from milliseconds down to one nanosecond. Typical samples are liquids in a cuvette, although measurements on powders or surfaces are possible.

  • Excitation Sources:
    • ozone-free Xenon arc lamp (230 nm – 1000 nm)
    • pulsed laser diodes (405 nm, 450 nm)
    • pulsed LED (280 nm)
  • Optics:
    • Excitation and emission monochromators
    • Excitation and emission variable polarization filters
    • Variable attenuation disk
  • Detector:
    • Photon counting photomultiplier tube
  • Accessories:
    • Temperature controller and thermoelectrically heated/cooled cuvette holder
