Abstract: A transmission Raman spectroscopy apparatus has a light source for generating a light profile on a sample, a photodetector having at least one photodetector element, collection optics arranged to collect Raman scattered light transmitted through the sample and direct the Raman light onto the at least one photodetector element and a support for supporting the sample. The support and light source are arranged such that the light profile can be moved relative to the sample in order that the at least one photodetector element receives Raman scattered light generated for different locations of the light profile on the sample.
