Abstract
The device includes a support tube passing through the wall of the column of the microscope, whose inner end is supported on an inner structure of the microscope by a hemispherical surface. This is supported in the wall around the orientation axis and is connected to the sample-holder which it traverses by control means enabling the position of the sample-holder to be adjusted in the support tube along three axes of a reference dihedral. The control means comprise an annular diaphragm for suspending the sample-holder in the support tube close to the center of the support surface. Lever and push-rod connecting linkages of high stiffness enable the sample-holder to be tilted around the center of the diagram in two perpendicular planes.
