Multidimensional Fourier Transform Infrared Spectrometer for Cost-Effective Laser Systems


Martin Zanni, Peter Hamm, Jan Helbing

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing a multidimensional spectrometer with simplified, cost-effective construction.
OVERVIEWTwo-dimensional spectroscopy can reveal interactions between coupled systems of atoms and/or molecules. Advanced spectroscopy techniques including two-dimensional infrared (2-D IR) and electronic (2-D E) laser spectroscopy have been developed in the last decade. Understanding of the physics and chemistry behind these techniques has matured to the point that applications ranging from energy research to chemical physics are now able to incorporate these technologies. Currently, applications are limited to research laboratory environments due to the high technological and cost requirements associated with the creation of a user-friendly multidimensional spectrometer. A 2-D IR and 2-D E spectrometer with a simple, robust and inexpensive design would allow these advanced techniques to be introduced to the commercial market.
THE INVENTIONA UW–Madison researcher has developed a simplified and robust multidimensional spectrometer that encodes frequency information into laser pulses traveling along two optical paths. This allows a multidimensional spectrograph to be generated.
  • Spectroscopic equipment component or add-on providing cost-efficient 2-D IR and 2-D E spectroscopy
  • Provides multidimensional spectroscopic measurements in the infrared, visible and ultraviolet regions of the electromagnetic spectrum
  • Facilitates measurement of inter- and intra-molecular interactions that can be used to study molecular binding, structures or kinetics
  • Simplifies construction of a multidimensional spectrometer, reducing cost for quick-to-market commercial applications
  • Reduces component cost by more than 30 percent
  • Permits flexible acquisition patterns that may be tailored for specific requirements
STAGE OF DEVELOPMENTA prototype has been constructed and is available to view upon approval by the researcher.
