PRODUCT DESCRIPTION

Edit Content

L900 provides control of the LP980 spectrometer, performance monitoring, transient absorption and emission decay data, time-gated spectra acquisition and data analysis, all in a straightforward manner.

A variety of different experimental settings and correction methods are available: pulsed or continuous probe operation, repetition rate control, automated subtraction of pump-only and probe-only backgrounds, maps of wavelength (kinetic detector), acquisition delay (spectral detector), or temperature.

The L900 software package offers a comprehensive library of data analysis routines as standard, including ΔOD calculation, 1- to 4-exponential and reconvolution fits, analysis of growth and decay kinetics.

The FLASH add-on is a separate package with additional tools for advanced transient absorption analysis.

Kinetic Transient Absorption from FLASH software

L900 features 4-exponential fitting of transient absorption decays, including reconvolution algorithms, as standard. 

Kinetic LIF

Kinetic Laser Induced Fluorescence Kinetic Laser Induced Fluorescence

Laser-induced fluorescence (LIF) decays are easily acquired with the standard PMT detector. L900 features allows acquiring a map by varying the wavelength automatically, and slicing the data to obtain time-resolved emission spectra. 

Spectral TA

Spectral TA

If the LP980 is equipped with an ICCD (LP980-KS), time-resolved spectra can be obtained in a single laser shot. L900 allows mapping the acquisition delay and displaying the result in 2D or 3D. 

Spectral LIF

Spectral Laser Induced Fluorescence

Setting a time map of the LIF spectrum is easy in L900. The user can set parameters such as the interval between acquisitions, the length of each acquisition, and the gain of the ICCD detector.
