    摘要: A facet mirror is to be used as a bundle-guiding optical component in a projection exposure apparatus for microlithography. The facet mirror has a plurality of separate mirrors. For individual deflection of incident illumination light, the separate mirrors are in each case connected to an actuator in such a way that they are separately tiltable about at least one tilt axis. A control device, which is connected to the actuators, is configured in such a way that a given grouping of the separate mirrors can be grouped into separate mirror groups that include in each case at least two separate mirrors. The result is a facet mirror which, when installed in the projection exposure apparatus, increases the variability for setting various illumination geometries of an object field to be illuminated by the projection exposure apparatus. Various embodiments of separate mirrors for forming the facet mirrors are described.

    摘要: The invention concerns a system for projecting a digital video image sequence using a light beam capable of being generated by a source (1) on a 3D swivel joint (2), of low/medium power laser type or white light laser type. The system comprises a shutter microdisc (4) with slots (3), two rotary optical discs (5) and (7) digitally interlocked on an axis (12) with 3D swivel joints (6), generating vertical and horizontal scanning of the screen, the whole assembly terminated by a rectangular shutter (8). The display is achieved by successive reflections of the light beam on microscopic reflecting facets arranged on the surface of the discs (5) and (7).

    摘要: The object of the invention is to provide an optical reflection plate having the following merits A - D. A. There is no need for expensive initial cost for a mold and the like for making a three-dimensional shape. B. Processing is simple and processing cost is low. C. The reflection plate shape after bending can be accurately retained and moreover the reflection plate is superior in dimensional stability even under endurance conditions. D. The attachment processing method for shape retention is simple, and the cost is low. To achieve the above object, the invention intermittently forms narrow cuts, along straight lines, that pass through from one-side surface to the other-side surface in a light-reflecting foamed plastic film or sheet. Thereafter, the film or sheet is bent along the cuts.
