September 19, 2006 Dinner meeting
The local meeting of the New York section of the Society of Applied Spectroscopy for September was held at the Horiba JobinYvon facilities in Edison, NJ on the 19th of the month. The Horiba staff hosted the visitors to an Open House with dinner – visitors were given a tour of the facility including the laboratories of the Fluorescence, Raman and XRF, Emission, Modular Optical Components, and Thin Films (Spectroscopic Ellipsometry) groups. For those who were interested, samples were brought and analyzed. After the tour and dinner, there was a talk given by Dr. Eunah Lee, highlighting one of the currently most active areas in Raman Microscopy; the title of the talk was
Hyperspectral Imaging using Raman Microscopy
Dr. Lee is an expert in Hyperspectral Imaging from her years at Spectral Dimensions, and has brought her insights to Raman mapping. The biggest impact has been to the characterization of pharmaceutical tablets and histological sections. To quote Dr. Lee’s abstract:
The available information in Raman Hyperspectral Imaging encompasses inherent Raman spectroscopic information (chemical identity, crystallinity, orientation, etc.), microscopic imaging information (spatial distribution of chemical species, size and distribution of chemical domains, etc.) and statistical characterization of the sample derived from variance among numerous spectra within the data set. The requirement for sample preparation is minimum and there is no damage to the sample. The results enable us to obtain a more comprehensive ‘picture’ of the sample.
The entire evening was relaxed and pleasant. The staff at Horiba JobinYvon look forward to a second similar event in the future where another of the spectroscopic techniques being manufactured right here in Central New Jersey will be highlighted.
