摘要:
A projection objective provides a light path for a light bundle from an object field in an object plane to an image field in an image plane. The projection objective includes a first mirror (S1), a second mirror (S2), a third mirror (S3), a fourth mirror (S4), a fifth mirror (S5), a sixth mirror (S6), a seventh mirror (S7), and an eighth mirror (S8). The light path is provided via the eight mirrors, and in the light path exactly one intermediate image of the object field is provided.
