For determining an alignment state of the secondary radiation source in relation to the illumination system, the illumination system comprises an alignment state determining system (ADS), wherein the alignment state determining system comprises an alignment detector (AD) configured to receive a portion of the EUV radiation emerging from the secondary radiation source and to generate therefrom an alignment detector signal (AS) representative of the alignment state.

The mirror module is embodied as a structurally exchangeable mirror module, and an optical alignment auxiliary component (AAC) is assigned to the illumination system, wherein with the aid of the optical alignment auxiliary component an alignment auxiliary signal (AAS, AAS') is generatable which allows a checking of the alignment state of the secondary radiation source or of an alignment state of an alignment mirror element after an exchange of the mirror module.
