The patent application provides an improved viewing port for an oceanographic submersible. It provides an optical path using multiple light transmissions between two especially configured reflectors carried on the exterior surface of an optical port. This construction obviates the need for structure extending outwardly from the oceanographic submersible and, additionally, permits cooperating equipment of several types to be used in conjunction with a single optical datum path. Further, the port used for support of the reflectors may be used as a general purpose viewport.
