  • Patent number: 9448384
    Abstract: The invention relates to an arrangement for mounting an optical element, in particular in an EUV projection exposure apparatus, comprising a weight force compensation device for exerting a compensation force on the optical element, wherein the compensation force at least partly compensates for the weight force acting on the optical element, wherein the weight force compensation device has a passive magnetic circuit for generating a force component of the compensation force acting on the optical element, and wherein at least one adjustment element is provided via which the force component generated by the passive magnetic circuit is continuously adjustable.
    Type: Grant

  • Patent number: 9410662
    Abstract: The invention relates to an arrangement for mounting an optical element, in particular in an EUV projection exposure apparatus, comprising at least one actuator which exerts a controllable force on the optical element; wherein between the actuator and the optical element a mechanical coupling in the form of a pin is embodied in such a way that, relative to the drive axis of the actuator, the ratio of the stiffness of the mechanical coupling in an axial direction to the stiffness in a lateral direction is at least 100; and at least one damping element which brings about a damping of a natural vibration form of the pin in a lateral direction.
