The device is connectable to a specimen-carrier table of non-eucentric type for the acquisition, by means of a scanning electron microscopic, of images taken in an angularly offset manner for stereoscopic examination of a specimen. A specimen-carrier table comprises a support member which is translatable along a first, vertical axis, as well as along a second and a third horizontal axis of which one is parallel and the other orthogonal to the interocular direction of the observer, and is turnable about its own axis as well as about the second axis. The accessory device comprises a support structure of metal material having a connection portion which allows fixing to the Movable member of the specimen-carrier table, as well as a support portion having a support surface which, when the said structure is coupled to the movable member of the table, lies in a plane parallel to the said axis of rotation, in such a way that after rotation of the movable member of the table through 90° about the said second axis, a subsequent rotation of the said movable member about its axis is able to cause the said surface to turn about the said third axis.
