| 摘要 |
The present disclosure relates to an optical device, in particular for microlithography, having an optical module, a supporting structure and a force-generating device. The force-generating device is connected to the optical module and the supporting structure and is designed to exert a clamping force on the optical module. The force-generating device has a fluidic force-generating element having a working chamber to which a working fluid having a working pressure can be applied. The force-generating element takes the form of a muscle element which exerts a first tensile force at a first working pressure and a second tensile force which is increased with respect to the first tensile force at a second working pressure which is increased with respect to the first working pressure.
