Abstract: The invention relates to an assembly comprising a interferometer for carrying out an optical coherence tomography, wherein the interferometer is divided into two spatially spaced-apart interferometer parts (1, 2), wherein the two interferometer parts (1, 2) can be moved related to one another and are optically connected to one another via flexible light guides (3, 4, 5), which bridge the spatial distance, wherein according to the invention, an assembly having an interferometer is provided, which is as unsusceptible as possible to the effects brought about by bending a tube cable packet and allows for an optimum signal-to-noise ratio or an optimum image quality of an OCT image, characterised in that at least one first flexible light guide (3) is designed as a polarisation-maintaining light guide consisting of two connected polarisation-maintaining light-guiding fibres (3a, 3b).
