An apparatus for the weight-compensating movable suspension of a focussingobjective(12) of a laser device (10) comprises a force generating arrangement forgenerating acounterforce component (G) counteracting the weight force of the focussingobjective (12),a transmitting arrangement that transmits the counterforce component (G) tothe focussingobjective (12) and as an up/down compensation movement of the focussingobjective, anda guide arrangement for movably guiding the focussing objective, in such a waythat duringan up/down compensation movement of the focussing objective (12) an opticalaxis (O)thereof maintains at least its spatial orientation and preferably its spatialposition.
