摘要： A display unit for binocular representation of a multicolor image including a control unit triggering an imaging element such that the imaging element generates in a temporal successive manner the image to be displayed for a first beam path and a second beam path as a first image and second image, respectively. The images are generated in a pre-distorted manner, opposite of the chromatic aberration of the respective beam path, such that the chromatic aberration generated in the respective beam path is compensated when the first and second image is displayed. The display unit includes a switching module which operates in temporal synchrony with the first and second image being generated, such that a user can see the first image only via the first beam path and the second image only via the second beam path.

摘要： The disclosure relates a projection objective of a microlithographic projection exposure apparatus, as well as a related microlithographic projection exposure apparatus and method. The projection objective can include a lens of a cubically crystalline material whose crystal orientation is oriented at an angle of at most 15° relative to the optical axis of the projection objective. The projection objective can also include a polarization correction element which has at least two subelements of birefringent, optically uniaxial material and having at least one respective aspheric surface. During use of the projection objective, the polarization correction element at least partially compensates for an intrinsic birefringence of the lens.

摘要： A polarization-selectively blazed, diffractive optical element including multiple contiguous blaze structures extending along a given geometrical path. Each structure has a width perpendicular to direction of extension greater than the Wavelength of the electromagnetic radiation for which the element is designed. Each blaze structure multiple individual substructures arranged next to each other in the direction of extension according to a predetermined period. The substructures providing the blaze effect have the shape, when viewed from above, of a closed geometrical surface whose dimension parallel to the direction of extension varies perpendicular to the direction of extension, but is always smaller than the wavelength of the electromagnetic radiation, and whose maximum dimension perpendicular to the direction of extension is greater than the wavelength of the electromagnetic radiation. The filling ratio of the individual substructures in the direction of extension relative to the period is selected such that, as a function of the position perpendicular to the direction of extension, the blaze effect is optimized for one polarization condition.
