  • Patent number: 4702565
    Abstract: In addition to providing fine adjustment for precise two-coordinate positioning of a specimen, a microscope stage has a handle for rapid displacement of the stage when the fine adjustment is disconnected. This handle is secured to the underside of the cross-slide (6) of the stage, and in a laterally central position of the stage; the handle also extends through a cut-out in the stage carrier, thereby defining the range of movement of the stage. The arrangement of the handle is ergonomically favorable and reduces the danger of contamination of the specimen. In addition, a rotatable sleeve on the handle enables fine and precise adjustment of the angular orientation of a chucked specimen, with respect to the microscope.
