Dispersive Raman Spectrometers

DISPERSIVE RAMAN SPECTROMETERS Raman shift range ... 

The Raman effect was discovered in 1928, but the first commercial Raman instruments did not start to appear until the early 1950s. These instruments did not use laser sources, but used elemental sources and arc lamps. In 1962, laser sources started to become available for Raman instruments, and the first commercial laser Raman instruments appeared in 1964-1965. The first commercial FT-Raman instruments were available starting in 1988, and by the next year, FT-Raman microscopy was possible (32). Due to the various complexities when one compares dispersive Raman spectrometers with FT-based systems (33), only sampling techniques will be discussed here.
