FT-Raman Microscopy: Discussion and Preliminary Results

Abstract

This paper reports on the first spectra obtained using a microscope apparatus to perform FT-Raman spectroscopy. It is considered desirable to use a standard FT-IR microscope for these measurements, since this approach may lead to the attainment of both FT-IR and FT-Raman microscope data from a single instrument. The relative performance of the microscope apparatus compared to that of a previously designed macro-apparatus is studied. The described micro-apparatus is then used to measure the FT-Raman spectrum of a single crystal of bis-methyl-styry I benzene and of a single fiber of Kevlar®. The results indicate an acceptable sensitivity, for these small samples.
