摘要： According to one exemplary embodiment, a projection objective (100, 200) is provided and includes at least two non-planar (curved) mirrors (M1-M4), wherein an axial distance between a next to last non-planar mirror (M3) and a last non-planar mirror (M4), as defined along a light path, is greater than an axial distance between the last non-planar mirror and a first refracting surface of lenses following in the light path. In one exemplary embodiment, the first refracting surface is associated with a single pass type lens. The present objectives form images with numerical apertures of at least about 0.80 or higher, e.g., 0.95. Preferably, the objective does not include folding mirrors and there is no intermediate image between the two mirrors, as well as the pupil of the objective being free of obscuration.

摘要： A catadioptric projection lens for imaging a pattern arranged in an object plane onto an image plane while creating a real intermediate image, having a catadioptric first lens section having a concave mirror and a beam-deflection device, as well as a dioptric second lens section that follows the catadioptric lens section, between its object plane and image plane. The beam-deflection device has a first reflective surface for deflecting radiation coming from the object plane to the concave mirror. Positive refractive power is arranged following the first reflective surface, between the latter and the concave mirror, within an optical near-field of the object plane, within which the height of the principal ray of the outermost field point of radiation coming from the object exceeds the marginal-ray height. The intermediate image lies well ahead of a second reflective surface that is provided for the purpose of allowing arranging the object plane and image plane such that they will be parallel to one another. A lens is provided between the intermediate image and second reflective surface.
