Abstract

An adjusting device for the specimen stage of an optical instrument such as a microscope or vernier measuring instrument comprising a pair of superposed slides mounted for movement in two mutually perpendicular coordinate directions perpendicular to the optical axis of the instrument with coaxial drive means for effecting fine adjustments of the positions of the slides and with a single, common release mechanism for simultaneously disengaging both drive means to facilitate rapid manual displacement of the slides to an approximate desired position.
