An adjusting device consists essentially of two angle pieces (3, 5) which fit into one another with a spacing between them, each having a leg (11, 16) extending in parallel with a stationary support (1). The horizontal leg (11) of the lower angle piece (3) is connected to the support (1) via a hinged joint, while a further hinged joint (4) connects vertical legs (12, 13) of both angle pieces (3, 5) to one another. On the horizontal leg (16) of the upper angle piece (5), the object to be adjusted is disposed either directly or in the receptacle (15) of an adjustable stage (9) mounted on the leg (16), for moving the object in the direction of the Z coordinate. The receptacle (15) is so designed that its centreline is in agreement with that of the object to be adjusted. Moreover, the vertical legs (12, 13) are dimensioned to have such lengths that the swivel axis of their hinged joint (4) lies horizontally in one plane next to the centre line of the object receptacle. By swivelling both angle pieces (3, 5) about the axis of the lower hinged joint, the object is displaced in the direction of the X coordinate, and by swivelling the upper angle piece (5) about the axis of its hinged joint (4), the object is displaced in the direction of the Y coordinate. <IMAGE> |
