Edinburgh - Model FLS1000 -Photoluminescence Spectrometer

• New Fluoracle® software package – easily accessible user interface and updated features
• Higher Resolution –  new 325 mm focal length monochromators provide superb accuracy and excellent stray light rejection with minimum step size
• Faster measurements – increased scan speeds and leading performance
• Increased automation – ease of use for even the most complex configurations

The system is a modular fluorescence and phosphorescence spectrometer for measuring spectra from the ultraviolet to the mid-infrared spectral range (up to 5,500 nm), and lifetimes spanning from picoseconds to seconds. All of this can be achieved through various upgrade routes, either at the time of order or in the future.

Whether you are studying photophysics, photochemistry, biophysics, biochemistry, material or life sciences, the FLS1000 will enable you to reliably and accurately measure luminescence spectra and kinetics using state-of-the-art sources, detectors, acquisition techniques, quality optics and precision mechanics. The large sample chamber will house practically any type of sample accessory.

High sensitivity is a prerequisite for measurements of low sample concentrations, small sample volumes or low sample quantum yields. The instrument’s guaranteed sensitivity of >30,000:1 (optional >35,000:1) for the standard water Raman measurement using the SQRT method is unmatched in the industry.

The FL1000 has a USB interface and all modes of operation are controlled by ONE data acquisition module and ONE all-inclusive Fluoracle software package for data acquisition and analysis. Light source, detector, grating, slits, polarisers are all computer-controlled for accurate and precise measurements.

Excitation Sources

The FL1000 comes standard with a 450 W ozone free xenon arc lamp that covers a range of 230 nm to >1000 nm for steady state measurements. A variety of other sources can be integrated including microsecond flashlamps, nanosecond flashlamp, pulsed diode lasers (EPL Series), pulsed light emitting diodes (EPLED Series), supercontinuum lasers, Ti:sapphire lasers, Q-switched solid state lasers and OPOs, dye lasers, and infrared CW and pulsed lasers for upconversion measurements.

Monochromators

Single and double grating Czerny-Turner monochromators are available in the FLS1000 with 325 mm (or 2 x 325 mm) focal length, high optical throughput, excellent stray light rejection and low temporal dispersion. The monochromators feature ‘plug-and-play’ triple grating turrets with up to three gratings on each turret and computer-controlled slits.

Detectors

A full range of detector options are available to enhance the range of spectral coverage and/ or to reduce the instrumental response width for lifetime measurements. The instrument comes standard with a PMT-900 detector in a cooled housing which covers a range from 185 nm – 900 nm, in TCSPC mode the instrumental response width is approximately 600 ps. Optional detectors include: high speed PMTs in a cooled housing with instrument response

Sample Holders

At the heart of the FLS1000 is an exceptionally large sample chamber that allows access to the sample from all sides, top and bottom. This ensures compatibility and simplifies access to a variety of sample holders.

• Type Czerny-Turner with `plug and play` triple grating turret
• Focal Length 325 mm (double monochromators: 2 x 325 mm)
• Slits 0 mm - 11 mm, fully computer-controlled, bandpass is grating dependent
• Stray Light Rejection 1:10-5 (single), 1:10-10 (double)
• Gratings Mounted to triple grating turret
• Accuracy +/- 0.2 nm *
• Minimum Step Size 0.01 nm *
• Option Spectral graphs available for operations of CCDs and diode array detectors

Fluoracle spectrometer operating software is at the heart of all our fluorescence spectrometers and is a fully comprehensive, user-friendly data analysis software package. Irrespective of system configurations, this software provides the user with complete control of the instrument and of most third-party accessories.

Fluoracle is Windows compatible and is based on a data centred design that enables the user to focus on their measurement. This guarantees ease-of-use in the operation of a modular and potentially complex spectrometer.

Measurement set-up and data acquisition is made through an intuitive menu system. Key spectroscopic parameters are easily accessed through functional groupings, while common measurement routines can be saved as method files to allow previous experiments to be easily repeated. Tabbed dialogue boxes and particular scan parameters are always visible during set-up. The current status of the instrument is also continuously displayed.

A unique feature of the Fluoracle is that all modes of data acquisition, including spectral scanning and lifetime acquisition in both MCS and TCSPC modes, are controlled from within one software package. Modern light sources, detectors, complex sample holders (plate reader, XY sample stages, titrator) and cooler options (thermostated sample holders and cryostats) are supported and fully software controlled.

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