    摘要: An optical beam transformation system, which can be designed to be utilized in an illuminating system of a microlithograpic projection exposure apparatus, has a sequence of optical elements arranged along an optical axis of the optical beam transformation system and designed for transforming an entrance light distribution striking an entrance surface of the optical beam transformation system into an exit light distribution emerging from an exit surface of the optical beam transformation system by radial redistribution of light intensity. The optical elements include at least one transformation element causing a radial redistribution of light intensity and having at least one transformation surface inclined to the optical axis and causing a polarization-selective reflection of a light distribution incident on the transformation surface according to an efficiency symmetry characteristic for the transformation surface. The optical elements further include at least one optical compensation element effecting a spatially dependent compensation of transmission inhomogeneties caused by the polarization-selective reflection at the transformation surface according to a compensation symmetry adapted to the efficiency symmetry of the transformation surface. Axicon elements with axicon surfaces may be used as transformation elements.

    摘要: An illumination system of a micro-lithographic projection exposure apparatus is provided, which is configured to illuminate a mask positioned in a mask plane. The system includes a pupil shaping optical subsystem and illuminator optics that illuminate a beam deflecting component. For determining a property of the beam deflecting component, an intensity distribution in a system pupil surface of the illumination system is determined. Then the property of the beam deflecting component is determined such that the intensity distribution produced by the pupil shaping subsystem in the system pupil surface approximates the intensity distribution determined before. At least one of the following aberrations are taken into account in this determination: (i) an aberration produced by the illuminator optics; (ii) an aberration produced by the pupil shaping optical subsystem; (iii) an aberration produced by an optical element arranged between the system pupil surface and the mask plane.
