  • Device for micropositioning of an object
    Patent number: 6452307
    Abstract: The invention relates to a device for micropositioning of objects, for example, in microscopy. The device comprises an accelerating means and a positioning unit connected therewith and connected with the object. The position of the object relative to the positioning unit can be changed at high acceleration or retardation of the accelerating means owing to mechanical inertia of the object. The positioning unit comprises at least two clamping elements between which the object is intended to be held merely by the clamping force and the frictional force exerted by these clamping elements.
