Abstract
An optical assembly of a microlithography imaging device comprises a holding device for holding an optical element. The holding device has a holding element having first and second interface sections. The first interface section for a first interface connecting the holding element and the optical element in an installed state. The second interface section forms a second interface connecting the holding element and a support unit in the installed state. The support unit connects the optical element to a support structure to support the optical element on the support structure via a supporting force. The holding device comprises an actuator device engaging on the holding element between the first and second interfaces. The actuator device acts on the holding element via a controller so that a specifiable interface deformation and/or a specifiable interface force distribution acting on the optical element is set on the first interface.
