The invention relates to studies of internal structures of objects with the aid of, optical means. According to the invention an optical system (15) of the delivering device, for low coherence optical radiation in a particular embodiment, an optical fiber probe (8), includes at least two lens components (19) (20), which have a positive focal , power and are positioned substantionally confocally. This ensures a constant propagation time for the, low coherence optical radiation propagating from a given point of the transverse scanning, surface (28) or (39) to a corresponding conjugate point of the image plane (22). That, provides elimination of the transverse scanning related aberration …
