Confocal Raman microscope

摘要

PROBLEM TO BE SOLVED BY THE INVENTION The object of the present invention is to provide a confocal Raman microscope with good analysis accuracy by detecting good Raman scattered light.An excitation light irradiating unit irradiates the excitation light to the sample, a collection of Raman scattered lights from the light scattered by the sample by using the confocal aperture, A confocal Raman microscope (10) comprising a light collecting means (3) for lighting and a detecting means (26) for detecting the collected Raman scattered light, The excitation light irradiating means 1 includes excitation light forming means 13 for forming a substantially annular cross-sectional shape of the excitation light, The light collecting means 3 is provided with a shielding means 22 for collecting the light in the substantially central portion of the light passing through the confocal aperture 20 and shielding the light on the outer side of the substantially central portion of the cross section Confocal Raman microscope 10.BACKGROUND OF THE INVENTION
