Abstract
A Raman probe for measuring Raman spectrum includes an exciting-end light guiding path for guiding excitation light from a light source to a sample; a receiving light-guide path for guiding a light signal from said sample to a detector; a band-pass filter for passing said excitation light and blocking Raman-scattered light produced from said exciting-end light guiding path; a pipe for securing said band-pass filter inside said pipe, said pipe being mounted on a light-outgoing end of said exciting-end light guiding path; and an edge filter mounted on a light-incident end of said receiving light-guide path, said edge filter passing Raman-scattered light from said sample while blocking the excitation light. The edge filter is a short-wavelength transmitting filter that permits passage of wavelengths shorter than the excitation wavelength.
