An apparatus for adjusting a microscope stage. The microscope stage of the apparatus defines a plane on which an object to be examined can be placed. The apparatus further includes a first shaft and a second shaft rotationally coupled to the first shaft. The microscope stage is guided between the first and second shafts such that a rotational movement of at least one of the first and second shafts has a direct effect on the microscope stage.

A device and method for adjusting mounting of a microscope stage (14), to which an objective (38) is mounted, to a microscope stand (12), including at least one first connecting element (56) arranged on the microscope stand (12), at least one second connecting element (62) arranged on the microscope stage (14) for mounting the microscope stage (14) to the microscope stand (12), at least one first mating part (76) arranged on the microscope stand (12), at least one positioning base (66) supporting a second mating part (74), wherein the positioning base (66) adjusts the platform (16) on the microscope stand (12) and is mounted movably in a plane of adjustment that is parallel to the platform (16) with the mating parts (74, 76) being engaged, and at least one locking device (80) for locking the positioning base (66) to the platform (16).
摘要:
The invention relates to a system for building automation, made up of a portable or handheld apparatus for situation-related information configuration and of at least one stationary unit, in which system the apparatus comprises a proximity sensor, a communication unit for wireless communication with at least one of the stationary units, an evaluation and control unit having at least one processor or logic unit and a memory, an information output unit, and an energy reservoir, the system being designed to create a wireless communication connection between the apparatus and at least one of the stationary units via the communication unit as a consequence of an approach by the apparatus, as ascertained by the proximity sensor, to at least one stationary unit, and to display a state of the at least one stationary unit via the information output unit.

The invention concerns a fine tuning device for moving and/or tilting an object. The inventive fine tuning device is characterized in that a support element can rotate about an axis of rotation being guided by a guiding element. To provide tilting between the support element and the guide element, a guiding plane is defined which intersects the axis of rotation by an angle other than 90°; to provide displacement, the object is fixed on the support element with a lateral offset relative to the axis of rotation.

A lifting stage includes a carrier frame, an object plate configured to carry an object, a cross-member, and a parallel articulation arrangement configured to articulate the object plate to the carrier frame so that the object plate is capable of being raised or lowered relative to the carrier frame without tilting. The parallel articulation arrangement includes a number of parallel articulations and connects the cross-member to the carrier frame and the cross-member to the object plate.
