Newport’s Two-Dimensional Spectrometer (2DSpec) is a state-of-the-art instrument for two-dimensional femtosecond spectroscopy. 2DSpec incorporates Newport's highest quality optics, opto-mechanics, spectrometer, vibration control, delay-line stage, and easy-to-use LabVIEW™ based software to deliver high quality results with consistency. Due to the flexible configuration and layout, 2DSpec can also easily be used for acquiring low noise femtosecond transient absorption spectra and can adapt to perform several other ultrafast spectroscopy techniques.
Flexibly designed two-dimensional femtosecond spectrometer that can also perform transient absorption measurements.
Supports a variety of ultrafast amplifiers and optical parametric amplifiers (OPA or NOPA) as input
Pump-probe (collinear) geometry for absorptive line shape and multi-color support
Control of pump-pump delay range and phase with the touch of a button. Supports phase cycling and rotating frame.
Robust, stable device is factory assembled and aligned for easy integration. Worldwide installation and support.
In comparison to traditional one-dimensional spectroscopy, where absorption or emission is measured as a function of energy (typically wavelength or frequency), two-dimensional spectroscopy allows analysis of the spectrum along two energy axes, exposing detail that is not present in one-dimension. These details consist of connections between electronic transitions, exciton – exciton coherences, population transfer, separate measurements of the homogeneous and inhomogeneous linewidth, or structural change to the molecules of interest.
