摘要: The present invention relates to an inertial slider (10) and a method for safely and controllably approach an object (2) towards a fixed object (3) for instance inside a transmission electron microscope (101). The inertial slider is controlled with a control signal (201) with a timing characteristic faster than a mechanical resonance of the object to be moved. The inertial slider moves in a first step away from the fixed object and the movable object is moved relative the inertial slider in that first step.

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 (3a), and the object (4) is provided with clamping elements (4'). These clamping elements (4') are adapted to clamp around said contact surface (3a) 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 (3a).

摘要: This invention relates to a measurement device (1) for use in an electron microscope (2), the device comprising a sample holder (3), for holding a sample (4) to be studied, and an indentation tip (5), being arranged in proximity of said sample holder (3), whereby an interaction between said sample and said tip is arranged to be measured. The measurement device comprises a force sensor (6), being positioned in proximity with an interaction area of said sample (4) and said tip (5), and being arranged to directly measure a force resulting from interaction between said sample (4) and said tip (5).
