Beschreibung
Zusammenfassung:	An optical module includes: a first holding device with a circumference extending in a first circumferential direction; and a plurality of first supporting devices configured to support a first optical element, the first supporting devices being fixed at the circumference of the first holding device. Along the first circumferential direction, at least one of the first supporting devices is located in a non-equidistant manner between two neighboring first supporting devices. The optical module is configured to be used in a microlithography objective.
