Beschreibung
Zusammenfassung:	The disclosure relates to an optical device, in particular for microlithography. The optical device includes an optical module and a support structure that supports the optical module. The optical module includes an optical element and a holding device that holds the optical element. The holding device includes a deformation device having a plurality of active deformation units which contact the optical element and which are designed so as to impose a pre-defined deformation on the optical element. The optical module is fixed to the support structure in a replaceable manner.
