Fluorometers (Fluorimeters)

A fluorometer (and fluorimeter) measures the fluorescence or light emitted by different fluorescing objects. Fluorescence occurs when light of specific wavelength hits and excites electrons in a sample, and the electrons in that sample instantly emit or fluoresce light of a different wavelength. All fluorescent objects have its own fingerprint, meaning that it excites and emits predictable types of light.

Fluorescent samples produce an emission spectrum that is measured through a monochromator connected to a photomultiplier detector similar to spectrophotometer.

After exciting a sample, a Fluorometer allow us to obtain and measure various attributes of that sample’s fluorescence, including its intensity, spectral wavelengths and lifetime. The fluorescence of a sample can be an indirect probe of the sample's environment, describing the solvent-solute interactions, inter- and intramolecular interactions, and so on. Fluorescence can be used for both qualitative and quantitative analysis of samples.

Analytical measurements provided by Fluorescence Spectroscopy Instrumentation are used in multiple applications including chemistry, biochemistry, medical research, pharmaceuticals, food science, environmental studies and nanotechnology. Fluorescence spectroscopy instruments have been used to examine counterfeit banknotes, materials for optoelectronics, and proteins.

Our Fluorometers can accommodate any size work-area, and are available as compact or benchtop models, or as large modular systems, to suit your requirements. In addition, our Fluorometers can be coupled to become modular Fluorometer systems, or supercontinuum white-light laser-powered lifetime Fluorometers!

HORIBA’s Fluorometers offer incredibly fast lifetime determinations down to picoseconds, deep UV absorbance and fluorescence excitation from as short as 200 nm in the UV, all the way to near-IR wavelengths of 1000 nm.

Aqualog A-TEEM, Industrial QC/QA Analyzer

The Aqualog

The HORIBA Aqualog® is a unique optical spectrometer that was initially invented to meet the needs of environmental water researchers around the world studying color dissolved organic matter (CDOM) using fluorescence spectroscopy. Today the Aqualog is the gold standard in CDOM water research, but it is also increasingly being applied with precision as a faster, less expensive and much easier analytical tool in industrial applications.


Webinars and Tutorials

To help you understand the various choices of Fluorescence Systems and the Fluorescence Spectroscopy applications for them, HORIBA Scientific presents a number of Tutorials and instructional Webinars.

Lifetime Fluorescence Spectrofluorometers

Lifetime fluorescence spectroscopy or time-resolved fluorescence spectroscopy investigates the change in fluorescence over time of a sample when irradiated with UV, visible, or near-IR light. This decay in fluorescence can be measured over a wide time range: from picoseconds to milliseconds and beyond.

Fluorescence Software

HORIBA Scientific offers Fluorescence Spectroscopy software tailored precisely for the types of experiments you perform. Our software runs through the Windows® environment, and controls all aspects of your system, from control of the slits at the entrance and exit ports of your spectrograph, to detector gain, system correction files, blank-subtraction, and automated batch-processing.

In addition, our software performs post-experimental modeling using the latest in mathematical techniques, and adds the power of an advanced graphical display and flexibility to export via many popular file-formats.

Steady-State Fluorescence Spectrofluorometers

Our steady-state fluorescence spectroscopy looks at the long-term average Fluorescence of a sample when irradiated with UV, Visible or near-IR Light.

These research-grade fluorometers are compact, benchtop or modular, and customizable for any sort of Fluorometry, be it Fluorescence detection or Phosphorescence studies your research requires.

Multifunction Steady-State and Lifetime Spectrofluorometers

HORIBA Scientific's multifunction fluorometers combine the best of both worlds: our multifunction instruments perform both steady-state and TCSPC lifetime fluorescence spectroscopy with the highest sensitivity and fast time resolution.
