Automated FLS980 Series Fluorescence Spectrometer

Edinburgh Photonics has designed a fully automated fluorescence spectrometer called FLS980, which is part of the proven FLS920 Series of fluorescence spectrometers supplied by Edinburgh Instruments. The FLS980 is a compact and flexible fluorescence spectrometer specifically designed for basic research and standard laboratory applications. Combined with excellent precision and high sensitivity, the FLS920 sets the benchmark for technical performance in luminescence spectroscopy.

The system’s flexibility allows users to include a variety of accessories and options to suit their specific application needs. Whether it is for studying semiconductor physics, biochemistry, photochemistry, biophysics, or photophysics, the FLS980 allows users to precisely measure luminescence in steady state and/or lifetime modes.

The system features a large sample chamber that can accommodate a wide range of sample holders and accessories.

High Accuracy and Sensitivity

The FLS980 provides improved sensitivity for spectral measurements which is essential for measuring small sample volumes and low sample concentrations.

The system offers 12000:1 Water Raman signal-to-noise and can be used with contemporary detectors and light sources. This capability allows lifetime and spectral measurements to be made from 200 to 1700 utilizing PMTs. Analogue detectors can be used to take temporal and spectral measurements from nanoseconds to seconds with flashlamps and pulsed lasers.

Advanced Software Package

Sophisticated software from Edinburgh Photonics controls the instrument and also contains routines for analysis. Users can design their experiments from their desktop, view their profiles built live on screen, and completely manipulate and analyze their data.

The FLS980 includes a USB interface; a single data acquisition module is used to control all modes of operation. This eliminates the need to reconnect or reconfigure cables for complex configurations.

Operational Modes

The FLS980 spectrometer can be customized to include one, two or three operational modes. The standard options include: Multi-channel scaling (MCS) mode for decays in nanoseconds to seconds range and Steady State Mode, a Time Correlated Single Photon Counting (TCSPC) mode for decays in picoseconds to microseconds range.

Phosphorescence lifetimes are generally measured by MCS, while fluorescence lifetimes are usually measured by TCSPC.


The FLS980 spectrometer is a flexible and fully automated system. A single acquisition module allows ultrafast data acquisition for TCSPC, MCS and spectral scanning. Advanced software package controls all modes of operation, analysis and presentation.

The FLS980 can be used with the latest light sources and detectors. Features like high performance monochromators with high straylight rejection, large sample chamber, and NIR upgradeability make the instrument suitable for routine laboratory applications.
