Abstract:
A projection objective with obscurated pupil for microlithography has a first optical surface, which has a first region provided for application of useful light, and at least one second optical surface, which has a second region provided for application of useful light. A beam envelope of the useful light extends between the first region and the second region. At least one tube open on the input side and on the output side in the light propagation direction severs to screen scattered light. The at least one tube is between the first optical surface and the second optical surface. The wall of the tube is opaque in the wavelength range of the useful light. The tube extends in the propagation direction of the useful light over at least a partial length of the beam envelope and circumferentially surrounds the beam envelope.

Claim (Index 38):
The apparatus of  claim 35 , wherein the tube is in the through hole.
