ABSTRACT:
The invention contemplates a binocular telescope wherein a bridge interconnects offset arms of separate individual telescope housings on spaced articulation axes, to enable compact folding of the telescopes along opposite sides of the bridge, when not in use. A first single control element provides ganged positioning control of corresponding focusing optical elements within both the respective telescope housings, and a second single control element provides independent adjustment of the focusing optical element within one to the exclusion of the other telescope housing. In the specific disclosed embodiment, a spring-loaded lost-motion connection between the ganged control structure and the mount for the focusing optical element enables the second single control element to provide for adjusted single-eye corrective accommodation without affecting the ganged focusing displacement produced by adjustment of the first single control element.
