Composite Or Echelon Mirrors Or Light Concentrating Array Patents (Class 359/851)
  • Patent number: 10312091
    Abstract: Methods, systems and devices for using charged particle beams (CPBs) to write different die-specific, non-volatile, electronically readable data to different dies on a substrate. CPBs can fully write die-specific data within the chip interconnect structure during the device fabrication process, at high resolution and within a small area, allowing one or multiple usefully-sized values to be securely written to service device functions. CPBs can write die-specific data in areas readable or unreadable through a (or any) communications bus. Die-specific data can be used for, e.g.: encryption keys; communications addresses; manufacturing information (including die identification numbers); random number generator improvements; or single, nested, or compartmentalized security codes. Die-specific data and locations for writing die-specific data can be kept in encrypted form when not being written to the substrate to conditionally or permanently prevent any knowledge of said data and locations.

    Abstract: An illumination optical unit for projection lithography has a first polarization mirror device to reflect and polarize of illumination light.

At least one drive device is operatively connected to at least one of the two mirror devices. The two mirror devices are displaceable relative to one another via the drive device between a first relative position, which leads to a first beam geometry of the illumination light beam after reflection at the second mirror device, and a second relative position, which leads to a second beam geometry of the illumination light beam after reflection at the second mirror device, which is different from the first beam geometry. This results in a flexible predefinition of different illumination geometries, in particular of different illumination geometries with rotationally symmetrical illumination.

  • Patent number: 8451527
    Abstract: A shutter includes micro-optics having first and second concentrator arrays. A transducer laterally displaces one of the first and second concentrator arrays between transmissive and shuttered modes. In the transmissive mode, the arrays of concentrators are optically aligned to permit electromagnetic energy passing through the first array of concentrators to pass through the second array of concentrators. In the shuttered mode, the electromagnetic radiation is blocked from passing through the second array of concentrators. The concentrators may be compound parabolic concentrators, or lenslets positioned on opposing plates with pinholes printed therethrough. The shutter may increase f-number of radiation passing therethrough, and may be used in a limited f-cone radiation source with shuttering abilities, for example reducing f-cone of radiation output from the radiation source.

    Abstract: A heads-up display system is configured for use in a vehicle. The system includes a standard vehicle window (i.e. no special coatings), an image projector, and a vehicle dashboard equipped with a faceted reflective surface. The image projector is configured to project an image onto the faceted reflective surface. The faceted reflective surface is configured to reflect the image from the image projector onto a window surface of the standard vehicle window. The window surface is oriented to reflect the image from the faceted reflective surface toward an occupant. The faceted reflective surface may be disposed within a plurality of troughs separated by a plurality of diffuse reflecting partitions. The plurality of troughs may be configured to shield the occupant from extraneous reflections. The faceted reflective surface may include a plurality of electrically controlled facets. The plurality of electrically controlled reflective facets may be an array of electrowetting cells.

  • Patent number: 8379310
    Abstract: Provided is a highly reliable solar collecting system. Since a concave minor has a reflection film on a base material on the side opposite to the side of a solar light incoming surface, peeling, breaking and the like are suppressed by protecting the reflection film by the base material, even when a dropping material is brought into contact with the side of the reflection film with impact or accumulated dropped materials are periodically cleaned. As an elliptical mirror has a reflection film on the base material on the side of the solar light incoming surface, even when solar light having large energy enters, the solar light is reflected by the reflection surface before reaching the base material and there is a small possibility of having the base material heated.

  • Patent number: 8251526
    Abstract: A spread primary reflector for a UV curing lamp employs a substrate that has been faceted. The facets may be produced by means of stamping, etching, or a combination of chemical-mechanical processes. The faceting randomizes the focusing effects of the primary reflector's elliptical curvature while maintaining a total directed energy output and hence a uniform irradiance of a work product. The reflector may be made of a stand-alone reflective material with a preformed faceting pattern, such as from a metal substrate and coated with an optical coating to tailor the reflective properties of the surface of the substrate.
