A multilayer thin film that reflects an omnidirectional structural color including a multilayer stack. The multilayer stack includes a reflector layer; a selective absorber layer extending over the reflector layer; an absorbing layer extending over the first layer; and a dielectric layer extending over the second layer. The multilayer thin film reflects a single narrow band of visible light when exposed to broadband electromagnetic radiation, the single narrow band of visible light having a center wavelength greater than 550 nm, and a visible full width at half maximum (FWHM) width of less than 200 nm. A color shift of the reflected single narrow band of visible light is less than 50 nm when the multilayer stack is exposed to broadband electromagnetic radiation and viewed from angles between 0 and 45 degrees relative to a direction normal to an outer surface of the multilayer thin film.

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.

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.

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.

In a known method for producing an emitter component with a reflector, a flowable aqueous SiO2 slip is produced using a slip method, and the slip is applied onto a quartz glass main part in the form of a slip layer. The slip layer is then dried and glazed, thereby forming a quartz glass layer which is more or less opaque and diffusely reflective. In order to produce an optical component with a reflective layer made of opaque quartz glass with increased reflective optical power, a method is proposed having the steps of: providing a main part with a surface which is at least partly coated with a reflective layer made of opaque glass, compressing a surface region of the reflective layer made of opaque glass, and applying a mirror-reflective layer on at least one part of the compressed surface region.

A field-enhancing device includes at least one metal layer or a metal grating consisting of metal stripes or a dielectric grating. Usually the device is constructed on some substrate. The adhesive layer is advantageous when the next layer is metallic but is not needed with dielectric layers. The next layers to be constructed form a mirror structure that can also be omitted for simple field-enhancing device constructs. The mirror structure can be either a metal mirror structure or a distributed Bragg reflector structure (DBR). The next layer is the thin metal layer. This layer can be covered with a 1-D metal grating consisting of metal stripes or with a dielectric grating having similar geometry. The structure can also be fabricated without metals when dielectric grating is used as the field-enhancing part. Finally, a protective layer can be added on top of the structure.

A lighting module is disclosed. The lighting module includes a light emitting diode (LED) light source, and a total internal reflection (TIR) optical assembly. The optical assembly includes a refractor configured to be located proximate to the LED light source, and a reflector configured to be attached to the refractor. The refractor is made from a material that is resistant to thermal damage when exposed to heat generated by the LED light source.
