LP980 Spectrometer

All-in-One spectrometer for Transient Absorption, Laser-Induced Fluorescence, Raman and Laser-Induced Breakdown Spectroscopy (LIBS)
Transients can be measured up to 2.55 µm to cover a wide range of samples and sample types
• Integrated ICCD allows transient spectra to measured within one laser flash
Advanced software package for complete computer control of all components and measurements


The LP980 sets the standard for technical performance required in a premier research instrument, offering unsurpassed measurement capabilties across a broad range of chemical, physical and biological applications.

Kinetic (K) and Spectral (S) Mode

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 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, Raman, fluorescence and phosphorescence lifetime measurement, and LIBS accessories are available as options.

Our tried and tested advanced software, the L900 package, is capable of dual mode measurement removing the need to make any manual mechanical adjustments. The software has an easy-to-use graphical user interface that simplifies a users ability to take measurements easily. Users can comprehensively manipulate data and perform analysis routines.
