Abstract
An optical probe assembly includes a light guide that includes a core region and a surrounding cladding region. The core region is constructed so as to minimize the creation of a relatively broadband spurious background noise signal when conveying the Raman pump light to the specimen, and the cladding region is constructed so as to satisfy the wave guiding reflection requirements of the Raman pump light and the Raman signature. A Raman spectroscopy system includes: a laser for producing Raman pump light; an optical probe assembly; and an optical spectrum analyzer for receiving the Raman signature of a specimen and identifying and characterizing the specimen based upon the spectrum of the Raman signature. Related methods are also disclosed.
