The Edinburg Instruments FLS1000 sets the standard in both steady state and time resolved photoluminescence
spectroscopy for both fundamental research and routine laboratory applications. The system is a modular fluorescence and phosphorescence spectrometer for measuring spectra from the ultraviolet (UV) to the mid- infrared spectral range, and lifetimes spanning from picoseconds to
seconds. FLS1000 enables to reliably and accurately measure luminescence spectra and kinetics using state-of-the-art sources, detectors, acquisition techniques, quality optics and precision mechanics. The instrument has an ultimate sensitivity of >30,000:1 for the standard water Raman measurement.

Sample Requirements:
1) We need a minimum 1 mL (3 ml preferred) completely dissolved liquid sample/~100 mg of solid powder sample. For thin films and pellet samples kindly discuss with FIC.
2) Absorbance (Optical Density) at the excitation wavelength of the sample should be around 0.1
3) Samples should not be toxic or hazardous. The same should be declared by the user while filling up the Sample Requisition Form.
4) Excitation wavelength and Emission Wavelength region should be given if already known.
Features:
The FLS1000 Spectrometer sets the standard in both steady-state and time-resolved photoluminescence spectroscopy for both fundamental research and routine laboratory applications. The system is a modular fluorescence and phosphorescence spectrometer for measuring spectra from the ultraviolet to the mid-infrared spectral range, and lifetimes spanning from picoseconds to seconds. 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. 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 >35,000:1 for the standard water Raman measurement using the SQRT method is unmatched in the industry.
Single Cuvette Holder: Temperature adjustable by water/coolant circulation, fitted with integrated probe for sample temperature monitoring by spectrometer operating software. Filter slots provided for holding 50 mm square filters. This sample holder is included as part of the standard system.
Magnetic Stirrer: Magnetic Stirrer to be fitted to single cuvette holder or 3- position sample turret. The stirrer comprises three stirrer bars and a stand- alone stirrer controller.
Powders, Thin-Films and Solids
Front-Face Sample Holders: A range of single position front-face sample holders are available for powders, thin-films and solids. These include linear staged holders, rotational holders and clamps.
Temperature holder specs
TE Cooled Sample Holder Standard Range (-10°C – +105°C): Thermoelectrically cooled 4-window cuvette holder with controller that enables stable temperature control of samples from -10°C to +105°C (-10°C with dry gas flow, 5°C without gas flow). The temperature can be held constant with ±0.02°C precision and can be rapidly changed. A magnetic stirrer (without stirrer bars) is included.
Polarisation/Anisotropy Specs
Standard Range (220 nm – 900 nm): Glan Thompson polarising prism. Spectral range 220 nm – 900 nm. The polariser can be automatically moved into or out of the beam. The position is recognised by the computer and the polarisation angle is fully computer-controlled. Automated anisotropy measurements are possible if both excitation and emission polarisers are present.
Integrating sphere for Quantam yield measurements specs:
The integrating sphere is a demountable accessory for the measurement of fluorescence quantum yields. It is 120 mm in diameter and has an inner surface coated with BenFlect to enable efficient scattering of light over a wide wavelength range. With the integrating sphere, the measurement of fluorescence quantum yields by an absolute method, as well as reflection measurements, are possible on solutions, film and powder samples. Holders for both direct and indirect excitation is provided. Two cuvettes and two powder trays are supplied as part of the sphere accessory. Options for electroluminescence and temperature dependent quantum yield measurements are also available.
TCSPC Electronics specs
