Binocular telescope

The invention contemplates binocular-telescope construction wherein a central bridge establishes spaced parallel pivot axes for separate articulation of the respective telescopes with respect to each other. Focusing-adjustment means carried by the bridge is operative upon corresponding movable optical elements of the respective telescopes, regardless of the articulated position of either or both of the telescopes with respect to the bridge. The chain of connection between adjustment at the bridge and optical-element positioning involves a longitudinally guided movable element near each articulation axis, and an end of the element contacts a flat surface associated with the mount for the optical element, such surface being in a plane normal to the longitudinal guide axis of movable element.
