ABSTRACT:
A binocular opthalmometer has rotatable imaging optics which provide an image of a referencing element (mire) to a binocular viewing assembly. The viewing assembly is held stable (horizontal) by referencing it to a fixed support or stand in which the rotatable optics are journaled. The referencing mechanism is provided by a shaft mounted for rotation about an axis radially spaced from the axis of rotation of the imaging optics and which is rotatably coupled at one end to the stationary support and at the other end to the viewing assembly.
