Latest Patent Applications

One of Hans-Jürgen Rostalski's significant patent applications is for an imaging optical unit. This innovative unit comprises a plurality of mirrors designed to image an object field in an object plane into an image field in an image plane. The application specifies that the image-side numerical aperture is greater than 0.55. Additionally, it outlines a ratio between an object/image offset and a meridional transverse direction of at least 0.5. Furthermore, the application details a ratio between the working distance from the object plane to the closest reflection portion of one of the mirrors and the meridional transverse dimension, which is at least 0.05. The working distance is specified to be at least 270 mm. This design aims to yield an imaging optical unit that is relatively manageable for use in projection exposure apparatuses, such as those utilized in EUV projection lithography.

Conclusion

Hans-Jürgen Rostalski's work in imaging optical units showcases his innovative spirit and dedication to advancing optical technologies. His contributions, although not yet reflected in granted patents, hold promise for future developments in the field.
