Radio frequency identification enabled mirrors
A radio frequency identification (RFID) enabled mirror includes a mirror comprising a reflective layer. The reflective layer comprises at least one layer of a metallic material. At least one portion of the reflective layer is removed to form a booster antenna from a remaining portion of the reflective layer. A dielectric coating is applied to the mirror where the reflective layer was removed. The RFID-enabled mirror further includes an RFID chip coupled to the booster antenna.
Coating stress mitigation through front surface coating manipulation on ultra-high reflectors or other optical devices
An apparatus includes an optical device that includes a substrate, a first layer of material over the substrate, and a second layer of material comprising an optical coating over the first layer of material. The first layer of material creates a first stress within the optical device that counteracts a second stress within the optical device created by the second layer of material. The optical device may also include a third layer of material positioned between the substrate and the first layer of material. In some cases, the second layer of material creates a compressive stress within the optical device, and the first layer of material creates a tensile stress within the optical device that counteracts the compressive stress within the optical device.
Galvanometer mirror and laser machine
A galvanometer mirror according to the present invention comprises: a transparent substrate; a laser beam reflection layer arranged on one surface side of the substrate and causing reflection of a laser beam having a predetermined wavelength; and a machining point beam reflection layer arranged on the other surface side of the substrate and having higher reflectivity for a beam having a wavelength except the predetermined wavelength than the laser beam reflection layer.
OPTICAL SYSTEM FOR DISPLAYING MAGNIFIED VIRTUAL IMAGE
An optical system for displaying a magnified virtual image of an image emitted by a display to a viewer. The optical system includes first and second lenses facing each other and spaced apart by an air gap to define an optical cavity therebetween. The optical cavity includes a reflective polarizer disposed on a major surface of the first lens, and an optical stack disposed on a major surface of the second lens. The optical stack includes an absorbing polarizer, a first retarder layer, a partial reflector, and a second retarder layer disposed between the absorbing polarizer and the partial reflector. The first and/or second lenses is/are birefringent lens provided outside the optical cavity to control polarization.
METHODS FOR ENCAPSULATING SILVER MIRRORS ON OPTICAL STRUCTURES
Embodiments of the present disclosure generally relate to encapsulated optical devices and methods for fabricating the encapsulated optical devices. In one or more embodiments, a method for encapsulating an optical device includes depositing a metallic silver layer on a substrate, depositing a barrier layer on the metallic silver layer, where the barrier layer contains silicon nitride, a metallic element, a metal nitride, or any combination thereof, and depositing an encapsulation layer containing silicon oxide on the barrier layer.
INTERFERENCE LAYER SYSTEM WITHOUT A CARRIER SUBSTRATE, METHOD FOR PRODUCING SAME, AND USE THEREOF
An interference layer system includes a plurality of optically transparent layers. The interference layer system has no carrier substrate and the optically transparent layers are disposed extensively over one another. The optically transparent layers are selected from the group consisting of dielectrics, metals, and combinations thereof, with at least one first optically transparent layer having a refractive index n.sub.1 and at least one second optically transparent layer having a refractive index n.sub.2, and with the first refractive index n.sub.1 and the second refractive index n.sub.2 differing by at least 0.1. The disclosure further relates to the production and the use of the interference layer system.
Radio frequency identification enabled mirrors
A radio frequency identification (RFID) enabled mirror includes a mirror comprising a reflective layer. The reflective layer comprises at least one layer of a metallic material. At least one portion of the reflective layer is removed to form a booster antenna from a remaining portion of the reflective layer. A dielectric coating is applied to the mirror where the reflective layer was removed. The RFID-enabled mirror further includes an RFID chip coupled to the booster antenna.
PRISM, OPTICAL DEVICE, METHOD FOR MANUFACTURING PRISM, AND METHOD FOR MANUFACTURING PACKAGE DEVICE
A prism is provided with which the positional accuracy can be effectively enhanced. The prism includes: a prism body 2 having a bottom surface 2a and an inclined surface 2b connected to the bottom surface 2a; and an adhesive film 3 provided on the bottom surface 2a, the adhesive film 3 including a first layer portion positioned on a side facing the prism body 2 and a second layer portion 6 including at least one of an Au layer or an Sn layer, the first layer portion 5 and the second layer portion 6 directly or indirectly stacked.
OPTICALLY VARIABLE SECURITY ELEMENT
An optically variable security element for securing valuable articles, has a relief grid having a plurality of relief elements arranged in a grid pattern and at least one line grid arranged vertically above or below the relief grid and having a plurality of line elements that run substantially in the same direction and that are location-dependently modulated. The relief grid and the at least one line grid coact to produce for a viewer, through the location-dependent modulation of the line elements, a surface that, with respect to the area of the security element, jumps out and/or back in the form of a specified three-dimensional image motif.
LAMINATE WITH LARGE AREA HUD AND SOLAR PROPERTIES
The invention provides for a coating which when used in conjunction with a p-polarization projector (26) and a windshield mounted such that the angle between projector is at or near the Brewster angle, a sharp image is produced with no ghost image. Further, the coating is suitable for use over the entire area of the windshield, has excellent solar control properties and has a low sheet resistance allowing it to be electrically defrosted at common automotive voltages.
