Abstract: A system provides for relative movement between two plates that are substantially parallel to a plane defined by a first direction and a second direction. The system includes a first unit that is configured to allow a relative movement between the two plates in a third direction that is orthogonal to the plane. The first unit also independently prevents a relative movement between the two plates in the plane. The system further includes a second unit that is configured to allow one plate to relatively travel with respect to the other plate about the first and second directions.

Abstract: The device (3) comprises a frame (6), a support piece (7) which is movable with respect to said frame (6) and which exhibits a master side provided with a rigid blade (9), on which may be fixed a first beam (2), and a slave side provided with two rollers, on which can rest an element for holding a second beam (2), and a set of actuators (13), which are able to position the movable support piece (7) in translation along two axes, termed the vertical axis and transverse axis respectively, which are perpendicular to one another and to a longitudinal axis, and in rotation about said longitudinal axis, so as to adjust the position of the first beam, the second beam following the translational motion along said two vertical and transverse axes.

Abstract: A specimen positioning mechanism includes a movable stage movable along multiple axes, a plate connected to and supporting a specimen mounting chuck, multiple linear displacement mechanisms coupling the plate to the movable stage and mutually spaced apart at different locations between the movable stage and the plate and separately controllable to change distances between the movable stage and the plate, and a flexible member coupling the movable stage and the plate. The flexible member is motion compliant in three axes of motion. The flexible member in response to linear displacements of the linear displacement mechanisms allows linear and rotational movement of the specimen mounting chuck in the three axes of motion compliance.
