Abstract

An FT-Raman microprobe based on a refracting microscope and proprietary beamsplitter is detailed and characterized with regard to spatial resolution, Rayleigh rejection, and performance as compared to a 180° backscattering macro-geometry. Several examples are presented which demonstrate the microprobe's capabilities in analyzing micro-samples with moderate Raman-scattering cross sections. Further improvements to the integrated system are also discussed and highlighted.
