BINOCULAR WITH OBJECTIVE LENS-BARRELS ROTATABLE ABOUT THE OPTICAL AXES OF THE OBJECTIVES |
摘要 |
A binocular comprising a binocular body, one or a pair of objective lens-barrel unit or units, a pair of eyepiece lens-barrels and a pair of image-erecting chambers. A pair of parallel optical axes pass through the objective lens-barrel unit or units. The image-erecting chambers are arranged between the objective lens-barrel unit or units and the eyepiece lens-barrels. The image-erecting chambers have incorporated therein their respective prism units for optically connecting the optical axes of the objective lens-barrel unit or units to respective optical axes of the eyepiece lens-barrel units. Each of the image-erecting chambers is associated with the binocular body for angular movement relative thereto about a corresponding one of the optical axes of the objective lens-barrel unit or units in such a manner that the optical axes of the respective eyepiece lens-barrel units are movable angularly toward and away from each other respectively about the optical axes of the objective lens-barrel unit or units.
