More Information
Summary:An optical arrangement, in particular to a lithography system, includes: a first component, in particular a carrying frame; a second component which is movable relative to the first component, in particular a mirror or a housing; and at least one stop having at least one stop face for limiting the movement of the second component in relation to the first component. The stop includes a metal foam for absorbing the kinetic energy of the second component when it strikes against the stop face. A method for repairing an optical arrangement of this kind after a shock load includes replacing at least one stop, in which the metal foam was compressed under the shock load, with a stop in which the metal foam is not compressed.
