Absorption spectrometer for ultrafast
phenomena
Turnkey system is ideal for the study of ultrafast phenomena such as electronic deactivation, intersystem crossing, vibrational relaxation, internal conversion and intra-molecular electron transfer
Newport has announced its new Helios transient absorption spectrometer "In recent years, researchers have pioneered many new techniques to study chemical reactions and the behavior of electrons in molecules using femtosecond laser spectroscopy"

"Today, we are able to better support these customers by offering a state-of-the-art, turn key, spectroscopy system for cutting-edge research applications," said Ron Hartmayer, Newport's director of marketing for photonics instrumentation.
"In fact, with our entire line of ultrafast solutions - from Newport's components, photonic instrumentation to the ultrafast laser systems such as the Spitfire Pro amplifier offered by our Spectra-Physics Lasers Division - Newport is the only company that is able to deliver complete ultrafast solutions that enable our customers to make, manage, and measure light".
Newport's Helios is a pump-probe transient absorption spectrometer, used to monitor extremely short-lived optically absorbing states.
The experimental time window ranges from 150fs to 3.2ns, covering wavelengths of 350 to 1600nm.
The system is completely turn-key, including all of the optics, optomechanics, the delay line and spectrometer in the optical unit and a PC, containing the data acquisition hardware and software.
The system is designed to work with an amplified Ti:Sapphire femtosecond laser.
The system captures the spectral and kinetic data required for investigating photoexcitation events on the sub-picosecond and longer timescale.
The system produces a 3D wavelength-time-absorbance data matrix in a form of an Ascii CSV file, which can be easily processed and displayed with proprietary software.
