Fluorescence spectrometer (Lifetime only)

LifeSpec II

The LifeSpec II is a compact, fully integrated, high performance fluorescence lifetime spectrometer designed for use with high-repetition rate pulsed femtosecond and picosecond lasers. The system is a fully automated solution, combining hardware and software in a single package for fundamental research and routine laboratory applications. The system's zero temporal dispersion optics set the standards for technical performance in measuring ultra-fast decays.

The LifeSpec II is compatible with Time Correlated Single Photon Counting (TCSPC) techniques and enables digital counting to reduce background noise, real-time direct measurement and observation and the extraction of long and short-lifetimes with large and small amplitudes from a single measurement.

The LifeSpec II features a temporally subtractive double monochromator. This provides spectral resolution, while at the same time eliminates the effect of temporal dispersion which prohibit accurate lifetime measurements in the lower picosecond time range.

Our advanced software both controls the instrument and allows ultrafast data acquisition and analysis that lets you to watch your profiles build live on screen and comprehensively manipulate and analyse data across the UV/Vis/NIR spectral range.

Data acquisition modes range from fluorescence decay and time-resolved spectra through to automated time-resolved anisotropy measurements and temperature maps. The shortest measureable lifetime is dependent on the speed of the detector and on the pulse width of the light source. By applying numerical reconvolution, lifetimes as short as 1/10th of the system’s instrumental response function can be extracted from the data, allowing the LifeSpec II to cover the range from 5ps - 50µs.

The LifeSpec II in the standard configuration is supplied with one detector. A configuration with two detectors can be specified on purchase. The LifeSpec II requires at least one picosecond pulsed diode laser, pulsed LED or Ti:Sapphire laser (with suitable pulse picker) for operation. The system is height adjustable so that the optical plane can be set between 130mm - 180mm.
