Title:
RAMAN SPECTROSCOPY DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/005073
Kind Code:
A1
Abstract:
The objective of the present invention is, in a Raman spectroscopy device, to prevent fluorescent light from a light-emitting element such as a lens and deriving from reflected light from a sample surface from being added to Raman scattering light as noise. The Raman spectroscopy device is provided with: a reflecting unit (203) that reflects an excitation light beam emitted from a light source (201) towards a sample surface in a direction perpendicular to the sample surface; an illumination focusing optical system (202) that focuses the light beam at the sample; a detection unit (207) that detects the scattered light back-scattered in the vicinity of the reflecting unit (203) and emitted by the sample. The portion of the excitation light beam reflected at the sample surface is shielded by the reflecting unit (203) and so does not head towards to the detection unit (207) side, and thus the entry of the excitation light to the detection unit (207) is prevented.
