Abstract
An adapter which may be employed in place of the main objective of a surgical microscope or other stereoscopic viewing microscope. The adapter housing contains two viewing objectives laterally separated from each other to define separate right-eye and left-eye viewing ray paths, and a separate illumination ray objective. A mirror behind this third objective deflects beams or rays of incoming illuminating light or laser radiation, coming from any appropriate source, so that it will pass through the third objective toward the object being viewed. The mirror is mounted for tilting movement in all directions, so that it may receive and properly direct light beams or laser radiation coming in from any appropriate direction. Prisms behind the two viewing objectives narrow the spacing of the two observation ray paths (e.g., to normal interpupillary distance) although the centers of the two observation objectives may be at a greater distance from each other, to provide a larger stereoscopic base.
