Abstract: A Raman analysing apparatus comprises an imaging optical system for imaging an object along an optical path to an optical detector, an irradiation optical system for illuminating the object, and a scanning device comprising a spinning pinhole disk. The irradiation optical system directs light onto the scanning device to illuminate the object at a plurality of illumination points. The imaging optical system images Raman scattered light emitted from the object at the illumination points to an intermediate image plane at which the scanning device is located. The imaging optical system may include a spectral filter and/or at least one optical spectral analyser. The apparatus enables high speed confocal Raman imaging and/or high speed confocal Raman spectography to be performed.

Abstract: A Raman spectroscopy apparatus comprises an imaging optical system that transmits light from an object to a spectrograph along an optical path. A scanning device intersects, and is movable with respect to, the optical path. Light is directed onto the scanning device to illuminate the object at a plurality of illumination points. The imaging optical system transmits Raman scattered light emitted from the object at the illumination points to an intermediate image plane, the scanning device being located at the intermediate image plane, and transmits the Raman scattered light from the intermediate image plane to the spectrograph. In comparison with conventional confocal Raman spectroscopy, the apparatus can perform Raman analysis of a sample more quickly, and in comparison with conventional line scan Raman spectroscopy the apparatus can perform Raman analysis more accurately.
