Abstract:
The disclosure relates to an assembly in a microlithographic projection exposure apparatus, with an optical element and at least one weight compensating device, which includes at least one magnetic circuit. A magnetic field generated by this magnetic circuit brings about a force for compensating at least partially for the force of the weight acting on the optical element. The apparatus also includes a coil arrangement with a plurality of coils. The arrangement is energizable with electrical current to generate a compensating force acting on the optical element. This compensating force compensates at least partially for a parasitic force that is exerted by the magnetic circuit when there is movement of the optical element and does not contribute to the compensation for the force of the weight acting on the optical element.

Claim (Index 7):
The assembly of  claim 1 , wherein the coil arrangement comprises:\n a first group of coils that are offset in relation to one another azimuthally with respect to a system axis of the weight compensating device; and a second group of coils that are offset in relation to one another azimuthally with respect to the system axis.
