A Raman system for use in performing Raman spectroscopy on a sample, comprises an optical source, a spectrometer, and an optical system for coupling light from the optical source to a sample and for coupling light from the sample to the spectrometer and a further spectrometer. A Raman system for use in performing Raman spectroscopy on a sample, comprises an optical source, a spectrometer and an optical system for coupling light from the optical source and a further optical source to a sample and for coupling light from the sample to the spectrometer. The optical system may be configured for coupling light from the optical source and the further optical source to the sample and for coupling light from the sample to the spectrometer and the further spectrometer. The Raman system may be portable and/or may be configured to be transported and/or carried and/or may be handheld.

Optical Raman system

An optical coherence tomography system for imaging a sample is configured so as to illuminate a region of interest of the sample with incident light from an optical source. The optical coherence tomography system is further configured so as to interfere, on an optical detector, reference light from the optical source with offset returning light emerging from the sample along an offset collection path which is spatially offset from the region of interest of the sample, thereby creating interference on the optical detector.
