    摘要: In EUV lithography apparatuses (10), it is proposed, in order to lengthen the lifetime of contamination-sensitive components, to arrange them in a protection module. The protection module comprises a housing (23-29) having at least one opening (37-47), in which at least one component (13a, 13b, 15, 16, 18, 19) is arranged and at which one or more gas feeds (30-36) are provided in order to introduce a gas flow into the housing (23-29), which emerges through the at least one opening (37-47). In order to effectively prevent contaminating substances from penetrating into the protection module, a light source (48-56) is arranged at the at least one opening (37-47), which light source illuminates the opening (37-47) with one or more wavelengths by which the contaminating substances can be dissociated before they penetrate through the opening (37-47).
