ABSTRACT:
The invention contemplates a binocular-telescope construction wherein no precision optical alignment or realignment procedures are needed within the telescope tubes, once the telescope tubes are assembled to their connecting bridge structure. The nature of the connecting bridge structure is such as to provide a range of universal action in the connection of each telescope tube to the bridge structure so that optical-axis parallelism can be mechanically effected and clamped at the universal connections without operating upon any of the individual optical elements within the telescope tube. The universal action and clamping is without prejudice to the single-articulated or double-articulated nature and action of the connecting bridge, for interpupilary-distance accommodation.
