Edinburgh Instruments, the world's leading manufacturer of luminescence spectrometers, has introduced a new version of its popular FLS1000 fluorimeter for measurements in the vacuum ultraviolet (VUV) region of the spectrum. Since VUV radiation (~10 nm to ~200 nm) is absorbed by air, maintaining vacuum conditions is essential for the spectrometer to function properly.
The FLS1000-VUV is available in 4 basic configurations:
| Designation | Excitation range, detection | Measurement mode |
| FLS1000-VUV-SVS2-s | VUV excitation & VIS detection | Steady state |
| FLS1000-VUV-SVS2-st | VUV excitation & VIS detection | Steady state & TCSPC (fluorescence lifetime) |
| FLS1000-VUV-SVSV-s | VUV excitation & VUV detection | Steady state |
| FLS1000-VUV-SVSV-st | VUV excitation & VUV detection | Steady state & TCSPC (fluorescence lifetime) |
Key Features:
- VUV excitation monochromator and D2 lamp covering 115 - 400 nm
- Up to two light sources and two detectors
- Vacuum sample chamber to maximize efficiency
- Holder for solid-state samples included
- Powerful TCSPC electronics for time-resolved VUV photoluminescence
- VUV emission arm with monochromator (up to three diffraction gratings) and vacuum photomultiplier
- Temperature dependence measurement capability using an optical cryostat
