A product comprising a substrate and a multilayer coating for the thermal control of a surface comprising a first inner layer intended to be deposited on said surface, a second intermediate layer applied on said first inner layer and a third outer layer applied on said second intermediate layer in which: said first inner layer comprises a co-dispersion of conductive nanoparticles and dielectric nanoparticles

A reflector (10), a method for manufacturing the same, a lens module (001), and an electronic device are provided, and pertain to the field of optical technologies. The reflector (10) uses a silicon-based substrate (101) with a planar structure as a base material, which can effectively reduce a volume and mass of the reflector (10) when compared with a right triangular prism. In addition, an included angle (γ) between a second side surface (1d) and a second surface (1b) of the silicon-based substrate (101) is designed as an obtuse angle, to ensure that after the reflector (10) is arranged in an inclined manner, a right angle protruding outward is not formed between the second side face (1d) and the second surface (1b).

One or more aspects of the present disclosure are directed to bladders that incorporate a multi-layer optical film that impart a structural color to the bladder. The present disclosure is also directed to articles including the bladders having a multi-layer optical film, and methods for making articles and bladders having a multi-layer optical film.

A display device includes a cover unit and a display panel coupled to the cover unit. The cover unit includes a first base member disposed on the display panel and including a first area and a second area when viewed in a plan view, a pattern layer disposed between the first base member and the display panel, a color layer disposed between the first base member and the pattern layer and having a light transmittance, and a reflective layer disposed between the display panel and the pattern layer.

A smart mirror attaches directly to a larger mirror, window pane, or other base structure in a fashion meant to appear as low profile as possible, meaning the smart mirror extends a very short distance outward from the mounting surface of the base structure, and there are no visible attachment devices. The smart mirror appears to be a part of the surface upon which it is mounted and appears to blend in seamlessly when the base structure is a mirror. Additionally, the smart mirror is easy to install onto the base structure with thin adhesive gel pads that leave behind no residue and are completely reusable. This enables the user to mount the device onto any smooth surface and to be able to easily move the device when desired. The smart mirror does not have any integral, built-in camera or microphone, but can be added as separate add-on peripheral modules.

An infinity mirror includes a light-transmissible and reflective layer, a reflective layer, a light-transmissible layer and at least one light-emitting element. The light-transmissible and reflective layer is disposed on a top surface of the light-transmissible layer. The reflective layer is disposed on a bottom surface of the light-transmissible layer. The at least one light-emitting element emits a light beam. The light-transmissible layer includes a pattern zone and a non-pattern zone. There is a height difference between the pattern zone and the non-pattern zone of the light-transmissible layer. The infinity mirror can provide a multi-mirror image effect.

A multilayer coating has a substrate, an optical layer, and a buffer layer between the substrate and the optical layer. The buffer layer has a coefficient of thermal expansion between that of the substrate and the optical layer. The multilayer coating has properties that enable its use in deep ultraviolet (DUV) wavelengths, such as for a multilayer mirror or edge filter. This multilayer coating with a buffer layer provides improved thermal stability and lifetime.

A substrate with a multilayer reflective film capable of facilitating the discovery of contaminants, scratches and other critical defects by inhibiting the detection of pseudo defects attributable to surface roughness of a substrate or film in a defect inspection using a highly sensitive defect inspection apparatus. The substrate with a multilayer reflective film has a multilayer reflective film obtained by alternately laminating a high refractive index layer and a low refractive index layer on a main surface of a mask blank substrate used in lithography, wherein an integrated value I of the power spectrum density (PSD) at a spatial frequency of 1 μm.sup.−1 to 10 μm.sup.−1 of the surface of the substrate with a multilayer reflective film, obtained by measuring a region measuring 3 μm×3 μm with an atomic force microscope, is not more than 180×10.sup.−3 nm.sup.3, and the maximum value of the power spectrum density (PSD) at a spatial frequency of 1 μm.sup.−1 to 10 μm.sup.−1 is not more than 50 nm.sup.4.

A lens for eyewear is configured to reduce the appearance of scratches on the lens and/or increase the durability of the lens. The lens can include a functional stack bonded to a lens body. The functional stack can include a functional layer, such as a thin film coating, sandwiched between the lens body and an optical-grade transparent film. The functional stack can increase abrasion resistance and environmental durability of the lens, and can reduce the appearance of scratches on the lens. The combined lens body and functional stack can increase the durability of the lens relative to a lens with a thin film coating (e.g., a gradient or mirror stack) on an external surface of the lens.

The present invention provides an optical film including a light reflection layer, in which the light reflection layer is a layer in which alignment of liquid crystal molecules is immobilized, the liquid crystal molecule forms a helical structure in a film thickness direction of the light reflection layer, and a tilt angle of the liquid crystal molecule is 15° to 55°. The present invention also provides a manufacturing method of the optical film including curing a polymerizable liquid crystal composition including a liquid crystal compound and a chiral agent interposed between a support and another support. In the optical film according to the present invention, an absolute value of oblique retardation is smaller. In the liquid crystal display device including the optical film, front surface brightness is high and an oblique change in the shade is suppressed.
