LifeSpec II: Fluorescence Lifetime Spectrometer
Brand: Edinburgh Instruments | Category: Nanotechnology
Dedicated fluorescence lifetime spectrometer using time-correlated single photon counting, with a 90 degree excitation and emission geometry. Temporal dispersion is negligible, which is what allows lifetimes down to 5 picoseconds to be resolved with a microchannel plate detector. A multi channel scaling upgrade extends the range to one second.

- Mini-tau: Fluorescence Lifetime Spectrometer
Compact lifetime spectrometer weighing 5 kg, covering both time-correlated single photon counting and multi channel scaling. A filter wheel with five bandpass filters replaces the emission monochromator, which is what keeps the instrument small and makes it suitable for teaching as well as routine lifetime measurement.
- FS5: Spectrofluorometer
Compact benchtop spectrofluorometer measuring both absorption and fluorescence in one instrument, with photon counting detection as standard. Sample modules are auto-recognised and swap in seconds, so the instrument moves between cuvettes, solids and plate formats without realignment. It upgrades to near infrared detection, time-resolved measurement, quantum yield and anisotropy.
- Plate Readers PR2 and SC-41: Microplate Reader Accessories
Microplate reader accessories for the FLS1000 and FS5 spectrometers, measuring fluorescence spectra and lifetimes from hundreds of wells in one acquisition while keeping photon counting sensitivity. The PR2 is the external module for the FLS1000, the SC-41 the internal module for the FS5.
