  • Publication number: 20220283509
    Abstract: An arrangement for use in a microlithographic optical imaging device includes an optical unit and a supporting structure for supporting the optical unit. The optical unit includes an optical element, a carrier structure for carrying the optical element, and an active actuating device. The optical element is supported on the carrier structure via of the active actuating device. The active actuating device is configured to adjust the optical element during normal operation of the optical imaging device in a maximum movement range, which is predefined by the normal operation of the optical imaging device, with respect to a first reference assigned to the imaging device. The active actuating device is configured so that the maximum movement range is completely covered by actuating movements of the active actuating device with an actuating accuracy predefined by the normal operation of the optical imaging device.

  • Patent number: 10754132
    Abstract: An imaging optical system, in particular a projection objective, for microlithography, includes optical elements to guide electromagnetic radiation with a wavelength in a path to image an object field into an image plane. The imaging optical system includes a pupil, having coordinates (p, q), which, together with the image field, having coordinates (x, y) of the optical system, spans an extended 4-dimensional pupil space, having coordinates (x, y, p, q), as a function of which a wavefront W(x, y, p, q) of the radiation passing through the optical system is defined. The wavefront W can therefore be defined in the pupil plane as a function of an extended 4-dimensional pupil space spanned by the image field (x, y) and the pupil (p, q) as W(x, y, p, q)=W(t), with t=(x, y, p, q).

  • Patent number: 10203607
    Abstract: An optical element unit including a first optical element module and a sealing arrangement is disclosed. The first optical element module occupies a first module space and includes a first module component of a first component type and an associated second module component of a second component type. The first component type is optical elements and the second component type being different from the first component type. The sealing arrangement separates the first module space into a first space and a second space and substantially prevents, at least in a first direction, the intrusion of substances from one of the first space and the second space into the other one of the first space and the second space. The first module component at least partially contacts the first space and, at least in its area optically used, not contacting the second space. The second module component at least partially contacts the second space.
