| 摘要 |
This invention relates to a device for micropositioning of an object ( 4 ), e.g. for use in a microscope. The device comprises an acceleration unit ( 1 ) and an intermediate part ( 3 ), connecting said acceleration unit ( 1 ) with said object ( 4 ). The position of the object relative to the acceleration unit ( 1 ) is variable at high acceleration or retardation of said acceleration unit ( 1 ), owing to mechanical inertia of the object ( 4 ). Further, the intermediate part ( 3 ) has a first end ( 3 '), being attached to said acceleration unit ( 1 ), and a second end ( 3 ''), being provided with an essentially circumferential contact surface ( 3 a), and the object ( 4 ) is provided with clamping elements ( 4 '). These clamping elements ( 4 ') are adapted to clamp around said contact surface ( 3 a) of said intermediate part ( 3 ) in order to hold the object ( 4 ) in relation to the intermediate part ( 3 ) merely by the clamping force and the frictional force exerted by said clamping elements ( 4 ') upon said contact surface ( 3 a).
