A field facet system for a lithography apparatus includes an optical element. The optical element includes a base section having an optically effective surface. The optical element also includes a plurality of lever sections provided at a rear side of the base section facing away from the optically effective surface. In addition, the field facet system includes two or more actuating elements configured, with the aid of the lever sections acting as levers, to apply in each case a bending moment to the base section to elastically deform the base section and thus to alter a radius of curvature of the optically effective surface. The actuating elements are arranged in series as viewed along a length direction of the optical element.
