Abstract: 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.

Abstract: A force sensor (200) and nanoidenation system (300) using such force sensor (200), wherein the force sensor (200) comprise a movable membrane (207) attached to a fixed bulk structure (210) with springs (201, 202, 203, 204) formed between the membrane (207) and bulk structure (210); the springs (201, 202, 203, 204) may be provided two on each side of a rectangular membrane(207) and each in the form of a U-shape with displacing elements (801) formed perpendicular to each open end of each U-shaped spring (800).

Abstract: This invention relates to a device for reducing the impact of undesired distortions when studying a sample in an electron microscope, wherein said sample is arranged to be mounted on a micro-positioning device, characterised in that said micro-positioning device is connected with a control device, being arranged to control said micro-positioning device so as to compensate for measurement errors due to undesired distortions.

Abstract: 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).
