ABSTRACT:
Coaxial drive for the object stage of a microscope, with a stationary guide supporting a first stage part which is horizontally displaceable in a first displacement direction. The first stage part supports a second stage part which is displaceable horizontally in a second displacement direction. A first control element displaces the first stage part in the first displacement direction and a second control element displaces the second stage part in the second displacement direction. The two control elements are rotatable about a coaxial axis and spatially retain their respective positions during displacement of the first stage part or second stage. A first force transmission device swivels about a second axis and displaces the second stage part. A second force transmission device acts on the second stage part. A rotating rod is provided between the first and second force transmission devices and transmit a rotation of the first to the second force transmission device. The rotating rod slides in the guide during the displacement of the second stage part, and either the guide or the rotating rod is swivelable about the second axis with the first force transmission device and is rotated by the first force transmission, and the force transmission is carried out by transmission of the rotating movement to the rotating rod or to the guide.
