Abstract:
A projection optical unit for EUV projection lithography has a plurality of mirrors for imaging an object field into an image field with illumination light. At least one of the mirrors is an NI mirror and at least one of the mirrors is a GI mirror. A mirror dimension Dx of the at least one NI mirror in a plane of extent (xz) perpendicular to a plane of incidence (yz) satisfies the following relationship: 4  LLWx/IWPV max <Dx.  A mirror dimension Dy of the at least one GI mirror in the plane of incidence (yz) satisfies the following relationship: 4  LLWy /( IWPV max  cos( a ))< Dy.

Claim (Index 14):
The projection optical unit of  claim 11 , wherein IWPV max  is at most 4\u00b0.
