Publication number: 20050185267Abstract: An infrared filter includes an optical filter stack disposed on a first surface of a substrate, the optical filter stack includes a plurality of dielectric layers and a plurality of metal layers alternating with the dielectric layers. and a transmission-enhancing coating. The infrared filter obtains an average transmission greater than or equal to 75% between 400 nm and 600 nm.Type: ApplicationFiled: February 23, 2004Publication date: August 25, 2005Applicant: Optical Coating Laboratory, Inc., a JDS Uniphase CompanyInventors: Georg Ockenfuss, Steven Oliver

Publication number: 20050185268Abstract: An anti-aliasing filter includes a polymeric double-refraction plate (“DRP”). The DRP of the anti-aliasing filter has at least a first liquid photo-polymerization (“LPP”) layer disposed on the substrate, or on an intervening layer(s) disposed on the substrate, and a first liquid-crystal polymer (“LCP”) layer is disposed on the first LPP layer, the first DRP having a thickness selected so as to provide a selected separation of oridinary and extraordinary light rays.Type: ApplicationFiled: February 23, 2004Publication date: August 25, 2005Applicant: Optical Coating Laboratory, Inc., a JDS Uniphase CompanyInventors: Anthony McGettigan, Georg Ockenfuss

Publication number: 20050100690Abstract: An transmissive panel includes a polymer coating with a textured antireflective surface. Texturing of the surface is achieved in a variety of fashions. In some embodiments the polymer coating is embossed after application to the panel. In other embodiments, the polymer coating is solvent-based and develops a textured surface as a result differential shrinkage. In yet other embodiments, an aerosol of solvent-based polymer precursor is applied to the surface as a combination of high-viscosity droplets and low-viscosity droplets, portions of high-viscosity droplets extending above a film of polymer formed from low-viscosity droplets to provide a textured antireflective surface.Type: ApplicationFiled: November 6, 2003Publication date: May 12, 2005Applicant: Optical Coating Laboratory Inc., a JDS Uniphase CompanyInventors: Thomas Mayer, Hiren Shah, Brad Duffy, Richard Zoborowski

Publication number: 20050088629Abstract: An image display system uses a polarizing beam splitter to direct light from a lamp to multiple spatial light modulators. The spatial light modulators (“SLM”) each generate an image portion, which are stitched together on a display screen to obtain a high resolution image. In a particular embodiment, image portions from two conventional SLMs, each controlling about two million pixels, are stitched together to form an image having about four million pixels. In another embodiment, two lamps are used with four SLMs to produce a resultant image having about eight million pixels.Type: ApplicationFiled: October 24, 2003Publication date: April 28, 2005Applicant: Optical Coating Laboratory Inc., a JDS Uniphase Company, a corporation of the State of DelawareInventors: Michael Greenberg, Matthew Bellis

Publication number: 20050024745Abstract: An optical thin film stack for a dark aperture is deposited using thermal ion-assisted deposition (“IAD”). The IAD provides an energetic deposition of chromium and chromium oxide that results in a dark mirror optical thin film stack with superior etch properties. Edge definition is improved, and the edge profile is controllable by the selection of IAD parameters. An in situ IAD cleaning process can be used to clean the substrate sufficiently so that an intermediate adhesion layer of chromium is not required.Type: ApplicationFiled: August 31, 2004Publication date: February 3, 2005Applicant: Optical Coating Laboratory, Inc., a JDS Uniphase CompanyInventor: Paul Gasloli

Publication number: 20040062043Abstract: A light integrator is mounted in a housing or cover that allows aligning the light integrator relative to a color wheel or other sequential color element. In some embodiments, a plate is attached to one end of a light rod and supports the light rod in the cover in a cantilever fashion or in combination with other support. The light rod is aligned to a light source, such as a lamp, and then the color wheel is aligned to the output of the light rod without altering the relationship between the light rod and the lamp.Type: ApplicationFiled: August 19, 2003Publication date: April 1, 2004Applicant: Optical Coating Laboratory, Inc., a JDS Uniphase Company and a corporation of the State of DelawareInventors: George B.
