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 1):
An assembly, comprising:\n an optical element; a weight compensating device comprising a magnetic circuit; and a coil arrangement comprising a plurality of coils, wherein:\n the magnetic circuit is configured to generate a magnetic field to produce a first force to at least partially compensate a force of the weight acting on the optical element; \n the plurality of coils is energizable with electrical current to generate a second force configured to act on the optical element to at least partially compensate a parasitic force exerted by the magnetic circuit when there is movement of the optical element; and \n the second force does not contribute to the first force.
