    摘要: Multilayer polymeric films and other optical bodies are provided. The films, which have at least three layers of different composition in the optical repeating unit, reflect light in a first portion of the spectrum while transmitting light in a second portion of the spectrum, exhibit improved reflectivities at oblique angles, and can be designed to suppress one or more higher order harmonics of the main reflection band.

    摘要: A multilayered reflective body which is thermoformable and capable of being fabricated into films, sheets, and a variety of parts while maintaining a uniform reflective appearance is provided. The reflective polymeric body includes at least first and second diverse polymeric materials of a sufficient number of alternating layers of the first and second polymeric materials such that at least 30% of the light incident on the body is reflected. A substantial majority of the individual layers of the body have an optical thickness of not more than 0.09 micrometers or not less than 0.45 micrometers, with at least one of the individual layers having an optical thickness of not more than 0.09 micrometers, and adjacent layers of the first and second polymeric materials differ from each other in refractive index by at least about 0.03.

    摘要: The present invention provides an optical interference film, made of multiple layers of polymers, which reflects wavelengths of light in the infrared region of the spectrum while being substantially transparent to wavelengths of light in the visible spectrum. The optical interference film includes multiple alternating layers of at least first, second, and third diverse, substantially transparent polymeric materials A, B, and C, with the layers being of an optical thickness of between about 0.09 and 0.45 micrometers. Each of the polymeric materials has a different index of refraction, n.sub.i, and the refractive index of the second polymeric material is intermediate the respective refractive indices of the first and third polymeric materials.

    摘要: A multilayer film indicator, mechanism and process for using the indicator for determining the integrity, authenticity, or conformance of an item to an original state, involving the measurement and comparison of the condition of the indicator to an identifiable original quality of the indicator. The identifiable original quality of the indicator is produced by the optical interactions of layers of diverse thermoplastic materials within a laminate of the indicator and is not readily visible to the naked eye.

    摘要: The present invention provides improved elastomeric interference films which are readily coextruded, have improved transparency, and have greater mismatches of refractive indices than those of the prior art. An improved elastomeric optical interference film comprising at least 100 alternating layers of at least first and second divergent substantially transparent elastomeric polymeric materials is provided. Adjacent layers of the first and second polymeric materials differ from each other in refractive index by at least about 0.05, and the thickness of the layers is from about 0.05 to about 0.5 micrometers. Stretching the films results in different wavelengths of light being reflected.

    摘要: An illumination assembly that includes a light guide and a plurality of light sources operable to direct light into the light guide is disclosed. The light sources have a center-to-center spacing of at least 15 mm, and a distance between a primary emitting surface of at least one light source of the plurality of light sources and the input surface is no greater than 1 mm. The assembly further includes a structured surface layer positioned between the plurality of light sources and the input surface. The structured surface layer includes a substrate and a plurality of structures on a first surface of the substrate facing the plurality of light sources. The assembly further includes a plurality of extraction features operable to direct light from the light guide through an output surface of the light guide.
