Abstract (en)

[origin: WO03036359A2] The invention concerns an optical element (1) with an optical axis (3), designed in particular for an exposure lens used in semiconductor lithography. Said optical element comprises at least an extension (2, 2') in the direction of the optical axis (3). A device (11) enables to induce a two-wave or multiple wave deformation in said optical element (1). At least a system (12) mounted in the extension zone (2, 2') is designed to apply a force in said extension (2, 2').
