A fluorescence spectrometer is a device to detect and analyze organic compounds. Used in biology, chemistry, and environmental science laboratories, the fluorescence spectrometer measures the fluorescence of a molecule to gather information about its components and chemical environment. The two main types of fluorescence spectrometers are filter fluorometers, which use filters to isolate the different types of light, and spectrofluorometers, which isolate the types of light with diffraction grating monochromators. When choosing a fluorescence spectrometer, consider the wavelengths it can analyze, the time analysis takes, and the amount of sample needed for analysis.

| Description | At the heart of the LP980 is a fully integrated and sophisticated transient absorption spectrometer. It uses the pump-probe technique for measuring transient kinetics and sepctra. In kinetic mode (K) a single point detector is used to measure the transient kinetics at a single wavelength (spectra At the heart of the LP980 is a fully integrated and sophisticated transient absorption spectrometer. It uses the pump-probe technique for measuring transient kinetics and sepctra. In kinetic mode (K) a single point detector is used to measure the transient kinetics at a single wavelength (spectra can be built up by automated scanning over a wavelength range and slicing the data). In spectral mode (S) a gated intensified CCD is used to capture the whole spectrum in the presence and absence of the pump laser pulse, meaning the whole spectrum can be generated after one laser pulse. The LP980 spectrometer has a dual sample chamber that enables users to reliably and accurately measure transient chemical and biological species up to 2.55 µm using the pump-probe technique AND laser-induced fluorescence lifetimes down to nanosecond time ranges.
Transverse sample excitation geometry comes as standard. Thin-film, diffuse reflection, fluorescence and phosphorescence lifetime measurement accessories are available as options....

The instrument has been designed for operation with modern picosecond and The LifeSpec-II is a compact, high performance computer controlled instrument for the acquisition and analysis of time resolved fluorescence, based on the technique of Time Correlated Single Photon Counting (TCSPC).
The instrument has been designed for operation with modern picosecond and femtosecond lasers, such our EPLs (Picosecond Pulsed Diode Lasers), EPLEDs (Picosecond Pulsed LEDs), Titanium Sapphire lasers and supercontinuum sources. These sources enable measurements of fluorescence lifetimes down to tens of picoseconds across the UV-Visibile-NIR spectral regions up to 1700nm.
The LifeSpec-II has the unique feature of having an integrated emission monochromator with zero temporal dispersion. As such, very short fluorescence lifetimes can be recovered without an error introduced by the propagation of light on wavelength dispersive elements, such as the monochromator gratings.
The integrated system features a large sample compartment, with room for many sample holder options, including multi-position sample holders, cryostats, X-Y position sample holders, etc.
The instrument further comprises of computer controlled attenuation of incident light from the laser, optional polarisers, two computer selectable laser input ports and two computer controlled detector exit ports.
A detector shutter is both interlocked to the sample chamber for protection against excessive ambient light, and is also linked to the detector current to protect against overexposure by the laser.
The LifeSpec-II comes in two versions. The first version contains one set of gratings for the operation in the spectral range 200nm to 1000nm. The second version contains two sets of gratings for the operation in the spectral range 200nm to 1700nm.... Read More |
