Upgrade of a Raman spectrometer

improvement of a conventional JEOL Raman spectrometer with a single channel photo multiplier detector is described. New optical components [fibers, mirror, lens, and charge coupled device detector (CCD)] have been chosen to design a high quality and easy-to-use instrument. Tests have shown that with this modified spectrometer, Raman spectra can be acquired of a quality comparable to the spectra obtained previously, but the time needed to obtain a spectrum is markedly reduced. Selected test spectra and a simple calibration procedure to obtain the wavenumber values from the band CCD pixel position are presented.
