Raman spectroscopy is a spectroscopic technique that probes vibrational states of molecules using, for example, visible light. It requires very little or no sample preparation, and can be employed to test gas, liquid, and solid materials. Advances in lasers and solid-state detectors have allowed Raman spectrometers to be inexpensive and portable, perhaps even contained in a cellphone.

This webinar will review the basic theory behind normal, resonant, and surface-enhanced Raman scattering. It will discuss the required hardware in a working Raman spectrometer, describe data analysis and presentation, and give examples of common applications. In addition, it will examine some of the market challenges and solutions.

You will learn about:
  • The basic setup of a Raman spectrometer.
  • Performance trade-offs associated with the limitations of hardware such as illumination lasers, diffraction gratings, and image sensors.
  • The factors that influence the choice of the illumination laser.
  • The most common applications of Raman spectroscopy.
About the presenter:
Slawomir S. Piatek, Ph.D.,professor of physics, NJIT.Slawomir Piatek, Ph.D., has been measuring proper motions of nearby galaxies using images obtained with the Hubble Space Telescope as senior university lecturer of physics at New Jersey Institute of Technology. Additionally, he has developed a photonics training program for engineers at Hamamatsu Corp. in New Jersey in the role of a science consultant. He has presented at various international conferences and webinars on important topics such as automotive lidar, flow cytometry, selection of photodetectors, and more. He earned his doctorate in physics at Rutgers, the State University of New Jersey.

Who should attend:
Anyone who performs Raman measurements to analyze the chemical structure and composition of samples; anyone who is interested in learning more about how Raman spectroscopy works and its various applications; researchers and technicians who use spectroscopic techniques in their work; and technical professionals who are involved in the design, development, evaluation, and/or implementation of spectroscopic instruments.
