title: A needle probe to detect surface enhanced Raman scattering (SERS) within solid specimen.
abstract: A needle probe has been developed to obtain surface enhanced Raman scattering data from within a solid specimen located remotely from the spectrometer. It produces the high signal strength of a single mode optical fiber but with a negligible fiber induced background. The observed Raman signal strength is comparable to that obtained with a microscope objective of the same numerical aperture in a conventional spectrometer arrangement and many times larger than that of probes using two fibers.
