The FLS1000 from Edinburgh Instruments is a Photoluminescence Spectrometer that has a spectral range of 200 nm - 1000 nm. It operates in three modes: Single Photon Counting (SPC), Time-Correlated Single Photon Counting (TCSPC), and Time-Resolved Single Photon Counting (Multi-Channel Scaling - MCS). This spectrometer has a sensitivity (water Raman) above 30000:1 (for SPC) and lifetime range of 10 ns - 50 s (for MCS) & 5 ps - 10 &mus (for TCSPC).
The FLS1000 has a Czerny-Turner monochromator with a plug and play triple grating turret with a focal length of 325 nm, stray light rejection of 1:10-5 (single) & 1:10-10 (double), and minimum step size of 0.01 nm. It has gratings mounted to the triple grating turret and an accuracy of ± 0.2 nm. This spectrometer uses 450 W ozone-free Xenon arc lamp, microsecond flashlamp, picosecond pulsed diode lasers (EPLs) & pulsed LED (EPLED) excitation sources with a pulse width of 1 &mus - 2 &mus & above 60 ps.
The FLS1000 has photomultiplier tubes with spectral ranges of 200 nm - 850 nm, 200 nm - 1010 nm, 500 nm - 1700 nm, 230 nm - 850 nm, and 200 nm - 870 nm. It detector has a dark count rate of less than 200 kcps and response widths of 180 ps, 400 ps, 600 ps, 800 ps & below 25 ps. This spectrometer supports Fluoracle® software, WindowsTM platforms, mathematical smoothing, integration, differentiation, 2D & 3D graphics, contour plots, chromaticity, quantum yields, multi-exponential reconvolution, and lifetime analysis. It is ideal for research and laboratory applications.
