Publication number: 20240103382Abstract: An imaging optical unit comprises a plurality of minors for imaging an object field into an image field. The imaging optical unit has an image-side numerical aperture greater than 0.55. Each mirror is configured so that it can be measured by a testing optical unit having at least one DOE with a predetermined maximum diameter for test wavefront generation. For the complete measurement of all reflection surfaces of the minors, a maximum number of DOEs of the testing optical unit and/or a maximum number of DOE test positions of the at least one DOE of the testing optical unit comes into play, which is no more than five times the number of minors in the imaging optical unit. The result is an imaging optical unit in which a testing-optical measurement remains manageable even in the case of a design with an image-side numerical aperture which is relatively large.Type: ApplicationFiled: November 29, 2023Publication date: March 28, 2024Inventors: Hans-Jürgen Rostalski, Holger Münz, Christoph Menke

Publication number: 20240094637Abstract: An imaging optical unit comprises a plurality of mirrors for imaging an object field in an object plane into an image field in an image plane. An image-side numerical aperture is greater than 0.55. A ratio between an object/image offset and a meridional transverse direction is at least 0.5. A ratio between a working distance between the object plane and a reflection portion, closest to the object plane, of one of the mirrors and the meridional transverse dimension is at least 0.05. The working distance is at least 270 mm. This can yield an imaging optical unit, the use of which is relatively manageable in a projection exposure apparatus, such as for EUV projection lithography.Type: ApplicationFiled: November 21, 2023Publication date: March 21, 2024Inventors: Hans-Jürgen Rostalski, Holger Münz, Christoph Menke

SPECTACLE LENS FOR A DISPLAY DEVICE WHICH CAN BE PLACED ON THE HEAD OF A USER AND GENERATES AN IMAGE
Publication number: 20240069362Abstract: A spectacle lens for a display device which can be placed on the head of a user and generate an image has a front and a rear, an injection section and a deflection section spaced from the injection section, an exit section in the rear and a light-guiding channel which guides light beams of pixels of the generated image, which are injected into the spectacle lens via the injection section, in the spectacle lens to the deflection section, by which they are deflected towards the exit section and then coupled out of the spectacle lens through the exit section. The spectacle lens is in the form of a progressive lens having a distance vision region and a near vision region, and the exit section, as viewed from above onto the rear of the spectacle lens, lies outside the distance vision region and outside the near vision region.Type: ApplicationFiled: November 8, 2023Publication date: February 29, 2024Inventor: Christoph MENKE -

Patent number: 11650510Abstract: A projection optical unit for microlithography includes a plurality of mirrors and has a numerical aperture having a value larger than 0.5. The plurality of mirrors includes at least three grazing incidence mirrors, which deflect a chief ray of a central object field point with an angle of incidence of greater than 45°.
