Abstract
A laser Raman microprobe separates a laser beam reflected by a sample and a Raman scattered light generated by the sample by a filter which transmits or reflects a light in a predetermined wavelength region including a wavelength region of the reflected laser beam and applies only the Raman scattered light separated by the filter to a single-monochromator for spectroanalysis. A high sensitivity analysis is attained by the single-monochromator.
