摘要： A method is provided of producing an optical filter. The method comprises depositing a first mirror layer onto a substrate; depositing an insulating layer on the first mirror; exposing at least some of a plurality of portions of a surface of the insulating layer to a dose of energy; developing the insulating layer in order to remove a volume from the at least some of the plurality of portions of the insulating layer, wherein the volume of the insulating layer removed from each portion is related to the dose of energy exposed to each portion, and wherein a remaining thickness after the removal of the volume from each portion of the insulating layer is related to the dose of energy exposed to each portion. The method further comprises depositing a second mirror layer on the remaining thickness of each of the plurality of portions of the insulating layer.

摘要： An omnidirectional multilayer thin film is provided. The multilayer thin film includes a multilayer stack having a first layer of a first material and a second layer of a second material, the second layer extending across the first layer. The multilayer stack reflects a narrow band of electromagnetic radiation having a full width at half maximum (FWHM) of less than 300 nanometers (nm) and a color of less than 50 nm when the multilayer stack is exposed to broadband electromagnetic radiation and viewed from angles between 0 and 45 degrees. In some instances, the multilayer stack has a total thickness of less than 2 microns (μm). Preferably, the multilayer thin film has a total thickness of less than 1.5 μm and more preferably less than 1.0 μm.

摘要： Disclosed herein are techniques for imaging in eye tracking. An imaging system for eye tracking includes a camera configured to detect light in a first wavelength range, a substrate configured to be placed in front of an eye of a user, and at least one reflector located within the substrate. The at least one reflector is configured to receive light in the first wavelength range reflected by the eye of the user, reflect at least a portion of the received light in the first wavelength range to the camera, and transmit light in a second wavelength range different from the first wavelength range to the eye of the user. The substrate is transparent to both the light in the first wavelength range and the light in the second wavelength range.

摘要： Thin multilayer reflectors are described. In particular, thin multilayer reflectors that partially transmit blue light and reflect green and red light are described. The thin multilayer reflectors have a uniform left bandedge across each dimension of the film, wherein the location of the left bandedge varies in a range of no more than 10% of the average left bandedge across that dimension.

摘要： A reflective transparent screen (1) capable of displaying an image light projected from a projector as an image to an observer who is on the same side as the projector, is provided with two transparent substrates and a metal thin film (23) sandwiched therebetween, wherein the color tone of the image light reflected from the metal thin film (23) or the image visibility is improved by adjusting the metallic composition of the metal thin film (23).

摘要： A nano-structure layer is disclosed. The nano-structure layer includes a plurality of nano-photonic structures that are configured in a first configuration such that light incident upon the nano-structured layer below a cutoff angle passes through the nano-structured layer and light incident upon the nano-structured layer above the cutoff angle is reflected back in direction of the incidence.

摘要： A plurality of bandpass filters (2) are arranged side by side in a row on a fixed surface (1a) of a glass block (1) and fixed using an adhesive (3). Each bandpass filter (2) includes a coating film (6) for transmitting or reflecting light depending on a wavelength. Each bandpass filter (2) includes a first surface (2a) fixed to the fixed surface (1a), and a second surface (2b) opposite to the first surface (2a) and having a width larger than that of the first surface (2a). Opposing side surfaces of the adjacent bandpass filters (2) include a first portion (2c) on the first surface (2a) side and a second portion (2d) on the second surface (2b) side. A spacing between the first portions (2c) of the adjacent bandpass filters (2) is wider than a spacing between the second portions (2d) of the adjacent bandpass filters (2).

摘要： As described above, one or more aspects of the present disclosure provide articles having achromatic structural color, and methods of making articles having achromatic structural color. The present disclosure provides for articles that exhibit achromatic structural colors upon exposure to white light (e.g., sunlight, artificial light, or a combination) through the use of an optical element, where achromatic structural colors are visible colors produced, at least in part, through optical effects (e.g., through scattering, refraction, reflection, interference, and/or diffraction of visible wavelengths of light). The optical element (e.g., a single-layer reflector or single-layer filter or a multilayer reflector or a multilayer filter; inorganic and/or organic material) can include a reflective layer(s) and/or a constituent layer(s).
