A mirror deflects an optical picture corresp. to a laser sight with marked-out reference direction and parallel in and outgoing laser beams in two directions at right-angles to one another. The mirror (1,2) effecting the final deflection works together with a servo system which turns it sideways (1,6-8) and is mounted on a platform over the whole of the appts. width, the turning of the mirror in a height direction being covered by another servo system 1,16). - At least one of the two servo rotations is linked outwards mechanically to the outside of the appts. and connected to unnits (30,23,20,21) sutable for mechanical transmission of movements to another mechanical free-standing but fixed-mounted instrument. A second fixed deflecting mirror (3) function can be taken over by a third mirror (4) by the second mirror being moved aside, thus freeing the third mirror whose mirroring surface is parallel to that of the second. - (Dwg.1/4) |
