A device comprising at least two body sections is disclosed. The first body section comprises a movable imaging unit and a magnet rigidly fixed to the imaging unit, and the second body section comprising an optical unit with a magnet rigidly fixed to the optical unit. The body sections are in a movable connection with each other, and the device is operable in at least two modes. In the first mode, the imaging unit and the optical unit are fixed in a set relative position due to magnetic interaction between the magnets. In the second mode, the imaging unit is positioned away from the optical unit.
