In an apparatus for positioning an optical element in a structure, particularly in an objective housing of a projection objective for microlithography, the optical element is connected to the structure via fastening elements. The position of the optical element is set by means of adjusting fasteners. The fastening elements are arranged in such a way and the adjusting fasteners can be actuated in such a way that the optical element can be tilted about three mutually independent axes and can additionally be displaced in a translatory fashion in one axial direction.

The invention relates to a positioning unit for an optical element in a microlithographic projection exposure installation. Said unit comprises a first connection region (A, 22) for connecting to the optical elements, and a second connection region (B, 20) for connecting to an object in the vicinity of the optical elements. At least two levers are connected to the second connection region by means of the respective lever bearing thereof, and the respective load arm thereof is connected to the first connection region by an articulation by means of an intermediate element (31, 33, 36) applied to said articulations. Regulating devices (28, 29) or actuators are arranged on the respective power arms of the levers. In a first position, the first connection region and the second connection region are arranged in relation to each other in such a way that the lever bearings of at least two levers and the articulations associated with said levers have approximately parallel rotational axes that are located approximately in a plane in the first position.

摘要:
An optical element module is provided. The optical module includes an optical element unit that includes an optical element and a support structure that supports the optical element unit. The support structure includes a support device and a contact device mounted to the support device. The contact device exerts a force on the optical element unit in a first direction via a first contact surface of the contact device. The first contact surface contacts a second contact surface of the optical element unit. The contact device includes a first linking section and a second linking section extending along a second direction running transverse to the first direction and arranged kinematically in series between the first contact surface and the support device. The first linking section and the second linking section are elastically deformed in response to a bending moment resulting from the force. The first linking section and the second linking section are arranged on opposite sides of a reference plane. The reference plane includes the force and runs transverse to the second direction.
