Patent number: 8729571Abstract: A light emitting device includes a number of light emitting diode dies (LEDs) mounted on a shared submount and covered with a single lens element that includes a corresponding number of lens elements. The LEDs are separated from each other by a distance that is sufficient for lens element to include separate lens elements for each LED. The separation of the LEDs and lens elements may be configured to produce a desired amount of light on a target at a predefined distance. In one embodiment, the lens elements are approximately flat type lens elements, such as Fresnel, TIR, diffractive lens, photonic crystal type lenses, prism, or reflective lens.Type: GrantFiled: March 21, 2012Date of Patent: May 20, 2014Assignee: Philips Lumileds Lighting Company LLCInventors: Walter Daschner, Xina Quan, Nanze P. Wang

Patent number: 6466371Abstract: A diffractive lens constructed in accordance with the invention comprises a set of bands such that the diffractive gratings in each band are modified. This is done to ensure that even if the lens is tilted (e.g. to prevent light from reflecting off the lens and, introducing distortion into an optical system), the lens continues to focus light onto a small point on a target surface. (The target surface is typically an optical or magneto-optic data recording medium.Type: GrantFiled: January 27, 2000Date of Patent: October 15, 2002Assignee: Aerial Imaging CorporationInventors: Walter Daschner, Bernard Kress

Patent number: 6330118Abstract: A magneto optic or optical disk drive comprises a laser source for providing laser beam, and a lens or compound lens for focussing the laser onto a currently inserted recording disk with specific overcoat thickness. In one embodiment, the lens is a compound lens that can focus aberration-free spots on different types of disk media having recording layers located under overcoats of different thicknesses. When a specific disk is inserted, only one spot in focussed onto the current recording layer. Furthermore, if the disk spins rapidly, it can wobble. The lens or compound lens comprises different regions where the focal length may vary slightly and continuously or discretely. Because of this, as the disk wobbles, the lens can nonetheless continue to focus laser light onto a small spot on the recording media, providing increased depth of focus in the vicinity of the currently inserted recording media.Type: GrantFiled: April 8, 1999Date of Patent: December 11, 2001Assignee: Aerial Imaging CorporationInventors: Walter Daschner, Barry Block, Arnold Thornton, Bernard Kress

Patent number: 6162590Abstract: A method for forming a novel head used in magneto-optic or optical disks comprises the steps of forming a diffractive lens on one side of a glass substrate and forming air bearing surface rails on a second side of said glass substrate. The glass substrate is then cut into separate heads. In this way, many magneto-optic or optical heads can be formed simultaneously without incurring the expense of bonding lenses onto a slider. In one embodiment, coils are deposited on the substrate to generate a magnetic field during magneto-optic write operations. In another embodiment, a glass wafer having diffractive lenses formed thereon is bonded to a silicon spacer structure.Type: GrantFiled: April 13, 1998Date of Patent: December 19, 2000Assignee: Aerial Imaging CorporationInventors: Barry Block, Arnold Thornton, Walter Daschner

Patent number: 6107000Abstract: A method for producing micro-elements, such as micro-lenses and computer generated holograms using a gray scale mask formed of a high energy beam sensitive glass plate which may be darkened by direct writing of an electron beam to record a gray scale pattern corresponding to a predetermined depth level to be etched into a photoresist coated substrate. The high energy beam sensitive glass may have a base glass composition which is provided with an ion exchanged surface layer containing a high concentration of silver ions. High energy beam sensitive glass plates are exposed to various electron beam charge densities at relatively low acceleration voltages and over relatively small grid spacings to provide a wide range of gray levels. Photoresist coated substrates are exposed through the gray scale mask and subsequently etched by chemically assisted ion beam milling to produce high efficiency micro-lenses and similar micro-elements having high surface resolution.Type: GrantFiled: December 17, 1996Date of Patent: August 22, 2000Assignee: Board of Regents - University of California - San DiegoInventors: Sing H. Lee, Walter Daschner

Patent number: 6033766Abstract: A method of producing a high resolution expanded analog gray scale mask is described. Using an inorganic chalcogenide glass, such as a selenium germanium, coated with a thin layer of silver, a gray scale mask may be produced with accurate control of the size, uniformity and variance of the pixels. The selenium germanium glass is composed of column structures arranged perpendicularly to the substrate giving a possible edge precision of 100 .ANG.. The column structures also prevent undercutting during the etching process, thus permitting pixels to be placed close together. Accordingly, selenium germanium may be used as a high resolution gray scale mask with an expanded analog gray scale. The gray scale mask may be used to impress information as a modulated thickness on a selenium germanium photoresist layer on an inorganic substrate. The selenium germanium photoresist layer may then transfer the gray scale to the substrate.Type: GrantFiled: January 11, 1999Date of Patent: March 7, 2000Assignee: Aerial Imaging CorporationInventors: Barry Block, Arnold O.
