Abstract

The invention relates to a system for optical coherence tomography having an interferometer (20) which has a beam splitter (24), a reflector (25), an illumination arm (21), a specimen arm (22) and a reference arm (23).In order to increase the compactness of the system with at the same time a high image quality a specimen objective is provided in the specimen arm (22) of the interferometer (20) by means of which light is focussed into a focus lying in or on the specimen (1). Moreover, in the reference arm (23) of the interferometer (20) a reference objective is provided by means of which light is focussed onto the reflector (25). The optical properties of the specimen objective differ from the optical properties of the reference objective.
