Abstract
Binoculars allow easy alignment of optical axes and correction of parallax in accordance with the distance of an object. The binoculars have correction lenses in right and left optical systems, and perform image-blur correction by moving the correction lenses in directions perpendicular to the optical axes and thereby inclining the optical axes. The binoculars also perform parallax correction by moving the correction lenses in accordance with the object distance and thereby inclining the optical axes such that the object images are kept at the centers of the right and left fields of view. Alignment errors that remain in the optical axes after assembly are eliminated by moving the correction lenses. This elimination of alignment errors is done every time the binoculars are used.
