<p>The invention contemplates a viewing-head attachment removably securable to the body of a microscope and adapted to accommodate binocular viewing elements. The attachment employs two housings which are pivotally connected so that the binocular-viewing elements on one housing are enabled to stereoscopically view an object examinable under the microscope body to which the attachment is secured. The quality of stereoscopic viewing is unaffected regardless of the instantaneous pivot-angle relationship as between the two housings, and no further optical adjustments are needed.</p> |
