Abstract: A light extraction film having nanoparticles with engineered periodic structures. The light extraction film includes a substantially transparent substrate, low index one-dimensional or two-dimensional periodic structures on the substrate, and a high index planarizing backfill layer applied over the periodic structures. Light scattering nanoparticles are either applied in a layer over the periodic structures or included in the backfill layer.

Abstract: A 3D imaging apparatus with enhanced depth of field to obtain electronic images of an object for use in generating a 3D digital model of the object. The apparatus includes a housing having mirrors positioned to receive an image from an object external to the housing and provide the image to an image sensor. The optical path between the object and the image sensor includes an aperture element having apertures for providing the image along multiple optical channels with a lens positioned within each of the optical channels. The apparatus also includes a transparent cover positioned within the optical path and having a plurality of fiducials. The depth of field of the apparatus includes the cover, allowing the fiducials to be used to calibrate the apparatus or verify and correct the existing calibration of it.

Abstract: A light extraction film laminated to a glass substrate for organic light emitting diode (OLED) devices. The light extraction film includes a flexible substantially transparent film, a low index nanostructured layer applied to the film, and a high index planarizing backfill layer applied over the nanostructured layer. A glass substrate is laminated to the flexible substantially transparent film on a side opposite the nanostructured layer and including an ultra-low index region between the film and the glass substrate. The ultra-low index region is used to reduce optical losses occurring with the glass substrate.
