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 40):
An objective configured so that, during use, useful light can propagate through the objective along a light propagation direction, the objective comprising:\n a first optical surface having a first region that interacts with the useful light during use of the objective; a second optical surface having a second region that interacts with the useful light during use of the objective; a third optical surface comprising a reflective surface and a through hole, the reflective surface comprising first and second portions and a through hole between the first and second portions, the first and second portions of the reflective surface interacting with the useful light during use of the objective; and a tube between the first and second optical surfaces along the light propagation direction, the tube having first and second openings, wherein:\n during use of the objective:\n a beam envelope of the useful light extends between the first and second regions; and \n an intermediate image is generated between the first and second optical surfaces so that the intermediate image is in the through hole and so that the tube is arranged at least in proximity to the intermediate image; \n \n the tube extends in the propagation direction of the useful light over at least a partial length of the beam envelope so that the tube circumferentially surrounds the partial length of the beam envelope and useful light passes through the tube between the first and second openings; and \n the objective is microlithography objective.
