    Abstract: Thickness and group index variations in test strip samples of ultra-low expansion glass are made by extracting the strip samples with front and back faces oriented at an acute skew angle to the axis of the boule. The strip samples are positioned the within an interferometric measurement cavity so that a set of subcavities formed by pairings of each of two reference surfaces together with each of the front and back faces of the strip sample which each subcavity having a different optical path length spacing. The skew angle is sized to avoid diffusion effects of striae present in the boule.

  • Patent number: 8928981
    Abstract: Sunlight redirector (30) incorporates closely proximate mirror arrays (32, 34) having parallel, uniformly spaced, longitudinal mirror segments (38, 44). Prismatic sheet (36) is positioned behind and closely proximate second array (34). Segments (38) extend in first direction (x). Segments (44) extend in second direction (y) perpendicular to direction (x) segments (38, 44)have normal vectors (42, 48). Segments (38) are interconnected for simultaneous pivotal movement (40), such that their normal vectors (42) remain parallel. Segments (44) are interconnected for simultaneous pivotal movement (46), such that their normal vectors (48) remain parallel. Arrays (32, 34) redirect incident light toward sheet (36), which redirects the light into a desired fixed direction, e.g. parallel to the sunlight redirect's normal vectors (50). Segments (38, 44) may have inward and outward segments (60A, 60B) which can be adjustably positioned to maximize redirection of incident sunlight rays in a desired direction.

  • Publication number: 20150002953
    Abstract: A mirror type display apparatus comprises a base substrate having a pixel region and a non-pixel region surrounding the pixel region, a driving device, a display device, a protective substrate and an island-shaped reflective layer disposed on a surface of the protective substrate. The island-shaped reflective layer including the island-shaped reflective layers separated by furrows formed on the protective substrate. The island-shaped reflective layer can minimize a warpage caused by a mismatch of coefficient of thermal expansion (CTE) between the protective substrate and the reflective layer.

  • Publication number: 20140368803
    Abstract: An illumination optical unit for EUV projection lithography guides illumination light to an illumination field, in which a lithography mask can be arranged. A facet mirror with a plurality of facets guides the illumination light to the illumination field. Respectively one illumination channel which guides an illumination light partial beam is predetermined by one of the facets. Exactly one illumination channel is guided over respectively one of the facets. The illumination optical unit is configured so that, at any time and at any point in the illumination field when the illumination optical unit is in operation, any pairs of illumination light partial beams guided over different illumination channels are incident on this illumination field point at times of incidence, the time difference of which is greater than a coherence duration of the illumination light.

  • Patent number: 8911099
    Abstract: Alternative methods of designing, developing and manufacturing optical elements and assemblies are provided which enable improvements in effectiveness and efficiency. Subtractive processes using lasers or other tools are utilized to create embedded void spaces that provide reflecting walls within internally reflective optical elements. The designs have advantages in cost, reduced development time, and performance. Light from multiple light sources can be mixed and collimated. Some embodiments provide the ability to integrate a large number of internally reflective optics into a single component and very large components can be made. Embodiments of the invention are designed for manufacturing and can be made without molding tooling.

  • Patent number: 8894226
    Abstract: A method for producing a multiple surface system that may be a two-mirror surface. The method involves first finding from a given primary curve an appropriate secondary curve. The method then uses ideas from exterior differential systems to grow from the primary curve and the secondary curve, primary and secondary mirror surfaces. The Cartan-Kähler theorem gives a strong indication of the existence of such solution surfaces.

  • Publication number: 20140300980
    Abstract: Two mirrors are encased in a padded fabric frame resembling a notebook that is secured to the body by adjustable neck and waist straps for hands free use. The device may also be hand held. Mirrors are set to the optimal angle for the user. The upper mirror reflects the forward/peripheral view, and the lower mirror displays this view as an upright image to the wearer. The conversation partner has an upright view of the wearer's face, as well. For bicycle use, smaller more rigid frame is recommended for placement on the handle bars.
