ABSTRACT:
An eccentric or off-center positive achromatic lens for attachment to the objective lenses of a binocular instrument in pairs, to the end that their counter-rotation, toward or away from each other, so moves the separate images formed by the two binocular telescopes as to fuse them into a single, stereoscopic image at approximately reading distance. The lenses are especially adapted to light-weight, high-quality spectacle binoculars, permitting the hands to remain free. They adapt such a binocular to become a stereomicroscope, ideal for highly-detailed dental work, micro-surgery and small-parts assembly. Suitable means is provided, in the form of a pair of grooved, rotatable tubes, containing the pair of asymmetrical lenses, to turn them in unison by means of an elastic belt to effect the stereoscopic fusion.
