摘要： A catadioptric projection objective for imaging a pattern onto an image plane includes: a first objective part for imaging the pattern into a first intermediate image; a second objective part for imaging the first intermediate image into a second intermediate image; and a third objective part for imaging the second intermediate image onto the image plane. A first concave mirror having a continuous mirror surface and a second concave mirror having a continuous mirror surface are upstream of the second intermediate image. A pupil surface is formed between the object plane and the first intermediate image, between the first and the second intermediate image, and between the second intermediate image and the image plane. A plate having essentially parallel plate surfaces is positioned in the first objective part near the pupil surface. At least one plate surface is aspherized to correct for aberrations.

摘要： A method of determining materials of lenses contained in an optical system of a projection exposure apparatus is described. First, for each lens of a plurality of the lenses, a susceptibility factor KLT/LH is determined. This factor is a measure of the susceptibility of the respective lens to deteriorations caused by at least one of lifetime effects and lens heating effects. Then a birefringent fluoride crystal is selected as a material for each lens for which the susceptibility factor KLT/LH is above a predetermined threshold. Theses lenses are assigned to a first set of lenses. For these lenses, measures are determined for reducing adverse effects caused by birefringence inherent to the fluoride crystals.
