A colored structure representing a back side-reflection color with metallic luster and high chroma when observed in a substrate incident mode greatly enhances light absorbance at a specific wavelength using a resonance structure in which a light absorbing material is inserted between a transparent substrate and an upper mirror layer. The colored structure controls metallic luster and texture of a high-chroma color from gloss-semi-gloss-matte texture in various aesthetic ways including introducing a haze surface structure in which light scattering occurs on at least one surface of the transparent substrate.

A display device may include a display unit disposed on a substrate and a mirror substrate facing the substrate with respect to the display unit. The mirror substrate may include a first mirror layer extending continuously on a surface of a transparent substrate and a plurality of mirror patterns on the first mirror layer. The first mirror layer is formed on both a region in which the plurality of mirror patterns are formed and a region in which the plurality of mirror patterns are not formed. External light is incident to and reflected by the first mirror layer, thus reducing an image haze and enhancing a display quality of the display device. In addition, the first mirror layer and the plurality of mirror patterns may be formed by using a single halftone mask to simplify the manufacturing process and increase a productivity of the mirror substrate.

An optical-thin-film structure comprises a low-index optical thin film consisting essentially of co-deposited Barium Fluoride and a secondary fluoride compound, and a high-index optical thin film.

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.

A support for optical elements is described. The support includes a base substrate with high specific stiffness and a finishing layer. The base substrate is a non-oxide ceramic material, preferably a carbide, such as boron carbide or silicon carbide. The finishing layer is preferably Ge or an alloy of Al and Si. The finishing layer is or is capable of being processed to provide a surface with low finish. Low finish is achieved by diamond turning or polishing the finishing material. The finishing layer has a coefficient of thermal expansion similar to the coefficient of thermal expansion of the base substrate. The optical element optionally includes a reflective stack on the finishing layer.

Provided is a wide angle application high reflective mirror having a reflection band partially overlapping in a wavelength range of 800-4000 nm. The mirror comprises a film system in which a plurality of high refractive index film layers and a plurality of low refractive index film layers that are alternately stacked, and the material of the high refractive index film layer is one of SiH, SiO.sub.xH.sub.y, or SiO.sub.xN.sub.y, or a mixture thereof. The highly reflective mirror can achieve a reflectance greater than 99% with an incident angle ranging from 0 to 60 degrees over a large angle range.

Optical-quality mirrors having an energetically bonded oleophobic/hydrophobic (O/H) coating are provided, as are methods for making and using such coatings and mirrors. The O/H coating is a thin-film coating that causes water and oils to form beads and become easily removable from the mirror surface, and thus improves the cleanability, contamination resistance, and usable life of the mirror.

A multilayer mirror having a cap with a multilayer structure including a top layer and a series of bilayers each having an absorber layer and a spacer layer, where the materials for the top layer, absorber layers, and spacer layers are chosen to resist blistering.

A stretchable reflective color-shifting film comprises a stretchable transparent polymer layer; a semi-transmissive metal layer; a transparent spacer layer; a reflective metal layer; an adhesive layer; and a stretchable base film layer. When the film body is stretched by 25%, the peak total reflectance stretched is at 80% of the peak total reflectance when the film body is unstretched according to the Total Reflectivity Test.

An optical filter includes a plurality of optical channels that each have a Fano resonance characteristic. A first optical channel, of the plurality of optical channels, is configured to pass a first portion of a first set of light beams (that are associated with a first wavelength range) and reflect a second portion of the first set of light beams when the first set of light beams falls incident on a particular surface of the first optical channel. A second optical channel, of the plurality of optical channels, is configured to pass a first portion of a second set of light beams (that are associated with a second wavelength range) and reflect a second portion of the second set of light beams when the second set of light beams falls incident on a particular surface of the second optical channel.
