Optical coherence tomograph (OCT) probe device ( 1 ) comprising an endoscope ( 6 ) which is adapted to be coupled to a light source ( 2 ) and has a distal tip portion ( 6.2 ), the tip portion ( 6.2 ) including focussing lens means ( 11 ) and a window ( 5 ) for directing light to a subject ( 7 ) to be scanned, and for receiving light scattered at the subject ( 7 ), to send the scattered light back through the endoscope ( 6 ) so that it may be applied to a detector ( 3 ) together with reference light, said OCT probe device ( 1 ) comprising a beam splitter ( 13; 17 ) to separate said reference light from the remaining light, as well as a reference light reflector ( 4; 20 ) for reflecting the reference light back so that it is composed to the light returned from the subject ( 7 ); the beam splitter ( 13; 17 ) and the reference light reflector ( 4; 20 ) are located in the tip portion ( 6.2 ) of the endoscope means ( 6 ) behind the focussing lens means ( 11 ) through which the composed light is sent back.
