  • Patent number: 10725208
    Abstract: Conductive nanoshells are oriented so as to redirect incident radiation as a function of wavelength. Nanoshells can be formed on templates such as nanospheres or gratings and embedded in an elastomeric layer. In some examples, conductive nanoshells are coupled to a layer that is configured to unbuckle and buckle as a function of temperature, so that radiation in one or more wavelength ranges is directed differently at different temperatures. Building windows can include such layers to that infrared radiation is reflected on warm days and directed into a building on cool days. Such layers can also direct incident visible radiation to a room ceiling so as to enhance interior lighting.

  • Patent number: 10613264
    Abstract: Multilayer optical film reflective polarizers previously considered to have excessive off-axis color can provide adequate performance in an LC display in an “on-glass” configuration, laminated to a back absorbing polarizer of the display, without any light diffusing layer or air gap in such laminate. The reflective polarizer is a tentered-one-packet (TOP) multilayer film, having only one packet of microlayers, and oriented using a standard tenter such that birefringent microlayers in the film are biaxially birefringent. The thickness profile of optical repeat units (ORUs) in the microlayer packet is tailored to avoid excessive perceived color at normal and oblique angles. Color at high oblique angles in the white state of the display is reduced by positioning thicker ORUs closer to the absorbing polarizer, and by ensuring that, with regard to a boxcar average of the ORU thickness profile, the average slope from an ORU(600) to an ORU(645) does not exceed 1.

  • Patent number: 10416569
    Abstract: An attenuation filter is configured to define attenuation of the intensity of ultraviolet radiation with a specified working wavelength from a wavelength range of 150-370 nm according to a specifiable local distribution in a projection lens of a microlithographic projection exposure apparatus. The attenuation filter has a substrate and an absorption layer on the substrate. The substrate is sufficiently transparent at the working wavelength. The absorption absorbs incident ultraviolet radiation of the working wavelength according to the specifiable local distribution at different locations of a used area to varying degrees. The attenuation filter reduces or avoids a thermally induced wavefront variation error in the ultraviolet radiation which has passed through the attenuation filter owing to locally varying heating of the substrate, which is caused by the absorption of the ultraviolet radiation that varies locally over the substrate. A thickness of the substrate is less than 100 ?m.

  • Patent number: 10393933
    Abstract: Tunable filters can use Fano metasurface designs having extremely narrow transmission bands. The Fano metasurface can comprise dielectric or semiconductor materials and can produce transmission bands with quality factors well in excess of 1000—at least a factor of 50 greater than typical metamaterial-based infrared resonances. Numerical simulations of these metasurfaces show that the spectral position of the passband can be changed by slightly changing the position of a small dielectric perturbation block placed within the near-field of the resonator by using simple electromechanical actuation architectures that allow for such motion. An array of independently tunable narrowband infrared filters can thereby be fabricated that only requires deep-subwavelength motions of perturbing objects in the resonator's near-field.
