PRODUCT DESCRIPTION

The FLS1000 Photoluminescence Spectrometer redefines excellence in steady-state and time-resolved photoluminescence spectroscopy, making it the go-to choice for both advanced research and routine lab work.

This modular system delivers precise measurements across a broad spectral range—from ultraviolet to mid-infrared (up to 5,500 nm)—and captures lifetimes from picoseconds to seconds. It also offers highly accurate absolute photoluminescence quantum yield measurements, with flexible upgrade options available at purchase or added later as your research grows.

No matter your application, the FLS1000 enables you to measure luminescence spectra and kinetics with unmatched accuracy using cutting-edge sources, detectors, and acquisition techniques. Its spacious sample chamber accommodates nearly any sample accessory with ease.

With industry-leading sensitivity of over 35,000:1 for the standard water Raman (SQRT method), this instrument excels at detecting weakly fluorescent samples.

All functions are seamlessly managed by Fluoracle®, an all-in-one software package for comprehensive data acquisition and analysis.

SOFTWARE

Figure 1: Fluoracle Software interface

Fluoracle® is a comprehensive, user-friendly software package for instrument control and data analysis at the heart of all Edinburgh Instruments fluorescence spectrometers. It provides the user with complete control of the instrument as well as third-party accessories irrespective of configuration.

Fluoracle is Windows compatible and features intuitive setup menus, live signal display, easy switching between measurement modes and user-friendly analysis wizards. This guarantees ease of use in the operation of a modular and potentially complex spectrometer. Common measurement routines can be saved as method files to allow previous experiments to be easily repeated.

Light sources, detectors, complex sample holders (microplate reader, XY sample stages, titrator) and cooler options (thermostated sample holders and cryostats) are fully software controlled. Fluorescence Lifetime Imaging Microscopy (FLIM) acquisition and analysis are included in Fluoracle with a MicroPL upgrade.

Fluoracle offers the FAST add-on for the advanced analysis of fluorescence and phosphorescence decay kinetics.

MEASUREMENT EXAMPLES

Besides standard excitation and emission spectra, Fluoracle can perform synchronous scans, excitation-emission maps (EEMs), and kinetic scans at a single or multiple wavelengths. The example shows an EEM acquired with a camera, which provides maximum acquisition speed acquiring a full emission spectrum in a single shot.

Temperature-dependent measurements and photoluminescence quantum yield are possible with suitable accessories. Cryostats, TE-cooled cuvette holders, and external cryostages for microscopes are all compatible and controlled by Fluoracle.

Using Batch measurement mode, customised series of scans can be set for a sample and measured automatically without the presence of the user. Loops and delays between scans can be programmed easily. The batch measurements (protocols) can be saved and loaded for future use. Communication with almost any external accessory is possible via a USB COM port command interface.

Steady state fluorescence anisotropy, singlet oxygen detection, chromaticity measurements, upconversion photoluminescence, electroluminescence, water quality assessments, absorption, and much more.

CUSTOMER TESTIMONIALS

OPTIONS AND UPGRADES

The FLS1000 Photoluminescence Spectrometer can be equipped with double monochromators on excitation and emission arms. Double monochromators are recommended for highly scattering, low emissive samples as they improve the system’s stray light suppression and increase the signal-to-noise ratio. A double monochromator in the emission arm allows for up to three detectors mounted simultaneously with software-based selection; two detectors can be fitted after the double monochromator and one after the first of the two monochromators.

If further detectors are required, the system can be configured in a T-geometry by the addition of a separate emission monochromator. This configuration can also be useful to provide a digital detection arm and an analogue detection arm.
