Abstract: There is provided an optical imaging device, in particular for microlithography, comprising at least one optical element and at least one holding device associated to the optical element (109), wherein the holding device holds the optical element and a first part (109.1) of the optical element contacts a first atmosphere and a second part (109.2) of the optical element at least temporarily contacts a second atmosphere. There is provided a reduction device at least reducing dynamic fluctuations in the pressure difference between the first atmosphere and the second atmosphere.

Abstract: A device or the operation of a device for the holding, especially sealing support of an optical element, especially an optical lens with at least one holding element for mounting the optical element and preferably at least one sealing element for sealing contact at at least a part of the optical element and/or the holding element, wherein the sealing element or at least a part thereof is displaceable between a first position, in which the sealing element rests against the optical element and a second position, in which the sealing element is spaced apart from the optical element, or wherein the sealing element is switchable such that it rests against the optical element under different contact pressure or adjustable contact force. The holding element can either take on the holding function alone and independently of the sealing element or work together with the sealing element in this regard.
