ABSTRACT:
A binocular wherein each telescope embodies a porro arrangement of mirrors within a shell and includes eyepiece and objective barrels. The objective regions of the telescope shells are hingedly connected together so that the interpupillary distance between the eyepiece barrels may be adjusted as desired, and the position of the hinge connection is such that the objective barrels are offset inwardly from the eyepiece barrels in any angular or adjusted position of the telescopes and to such an extent that no part of the binocular is projected in any manner into the rim region of the field of view when the binocular is put to use.
