Abstract: According to an aspect of the present inventive concept there is provided a light transmission system (100, 200) for delivering light to a Raman spectrometer (20), the system comprising: a homogenizer (110, 510) with an entrance surface (112, 512) having an entrance height and an entrance width, an exit surface (114, 514) having an exit height and an exit width, and wherein the exit height is of a larger size than the entrance height; and wherein the homogenizer (110, 510) is configured to receive, at the entrance surface (112, 512), light from a bundle (210) of optical fibers (220) and wherein each fiber (220) in the bundle (210) defines an entrance divergence angle of light; and wherein the homogenizer (110, 510) is configured to transmit light such that an exit divergence angle of light, in a plane parallel with a direction of the exit height, is smaller than the entrance divergence angle of light, in a plane parallel with a direction of the entrance height.
