    Abstract: Se presenta un artículo de vidrio que tiene un recubrimiento para el control solar, que se utiliza en la produccion de vidrio que reduce el calor en las ventanas para la construccion. El artículo recubierto incluye un sustrato de vidrio, una capa intermedia que suprime la iridiscencia depositada en y que se adhiere a la superficie del sustrato de vidrio. Al menos un primer recubrimiento transparente depositado en y adherido a la superficie del recubrimiento que suprime la iridiscencia y al menos un segundo recubrimiento transparente en y adherido a la superficie del primer recubrimiento transparente. El primer recubrimiento transparente y el segundo recubrimiento transparente tiene una diferencia en los índices de refraccion en la region de infrarrojo cercano mayor a una distancia en los índices de refraccion en la region visible. El uso del artículo en las ventanas de las construcciones resultan en una ventanas que rechazan la energía solar en la region del infrarrojo cercano mientras que permite la transmitancia de un alto grado de luz visible.

    Abstract: La presente invencion se refiere a una pelicula que refleja interferencia de capas multiples que tiene capas opticas opcionales arregladas para formar unidades de repeticion opticas en toda la pelicula. Cada una de una pluralidad de unidades de repeticion opticas tiene seis capas individuales, al menos tres de las cuales tienen diferentes indices de refraccion a una longitud de onda de diseno (0. Las capas individuales que tienen nominalmente el mismo indice de refraccion y espesor fisico, etiquetadas arbitrariamente "A", "B", "C" o "D", se arreglan en una unidad de repeticion optica de seis capas en una permutacion ciclica de CACDBD, donde las capas A y B son cada una mas gruesas que las capas C y D. Los espesores e indices de refraccion de las capas individuales se pueden seleccionar para suprimir las reflexiones de segundo, tercer, y cuarto orden, mientras reflejan la luz a la longitud de onda de diseno.

    Abstract: A hard to simulate, readily distinguishable from counterfeits, optical interference authenticating device comprises a substrate, and at least one optical interference, form depicting coating on the substrate and partially covering the substrate to delineate a known, distinct and readily distinguishable form thereon. The said at least one optical interference coating comprises at least one optical interference layer having known spectral reflectance and spectral transmittance characteristics when viewed at at least one particular angle so that the form is visible in particular colouration at the or each said particular angle of incidence of light thereon by reflected or transmitted light. At least one other optical interference coating may be provided on the substrate and may completely cover one side of it and the substrate may be transparent, semi-transparent or opaque, depending how the spectral characteristics are to be observed. A marginal edge portion of the form depicting coating may taper in thickness to provide a multi-coloured auriole around the form. When a plurality of form depicting coatings are provided they may partially overlie one another to provide a more complex pattern.

    Abstract: A thin film optical filter having a bandpass reflectance characteristic with one otthe transition wavelength edges thereof being non-polarizing for radiation incident at a preselected non-normalangle. The filter comprises a transparent substrate and a multilayer thin film optical coating provided on one surface thereof. The optical coating includes a preselected number of alternate layers of a first higher refractive index dielectric material and a second lower refractive index dielectric material arranged as a sequence of dielectric multilayer stacks with intervening spacer layers formed of one of the dielectric materials. The optical thickness of the spacer layers is detuned from half-wave optical thickness to shift either the low wavelength transition edges (Figure 10B) or the high wavelength transition edges (Figure 10A) for the separate bandpass response characteristics for the two principal polarization planes substantially into alignment with each other. Various other dielectric stack designs utilizing detuned layers to accomplish the same alignment of wavelength transition edges are described. Simplex and duplex fiber optic communication systems utilizing non-polarizing edge filters of the thin film type are also disclosed.

    Abstract: A multi layer interference coating comprising at least one multi layer stack deposited on a reflective layer (9), wherein each multi layer stack comprises a first dielectric layer (11), a layer of absorbing material (10) and a second layer of dielectric material (11) arranged in series and having a reflectance spectrum in the infrared region comprising at least one maximum. The dielectric layers are of equal optical thickness and typically are of the same material. The multi layer structure of the coating is such that incident electromagnetic radiation, for which odd multiples of half wavelengths correspond to the optical thickness of the multi layer coating at the incident wavelength do not propagate within the coating and reflection at these wavelengths, is suppressed. Coatings may therefore be designed to have a near satured colour in the visible wavelength spectrum. The reflective layer may be a metal or a conducting oxide, a conducting nitride, a conducting silicide or a conducting sulphide. The absorbing layers may be Cr, V, Pd, Ni, Pt, conducting oxides, or substoichiometric metal oxides, such as TiOx. In one form of the coating, where a non-metal absorber is used, the second dielectric layer may be removed in at least one of the multi layer stacks. The coating may be incorporated in a system for verifying the authenticity of an article.

    Abstract translation: 多层干涉涂层，包括沉积在反射层（9）上的至少一层多层堆叠，其中每层多层堆叠包括第一介电层（11），吸收材料层（10）和第二层电介质材料 （11），其在包括至少一个最大值的红外区域中具有反射光谱。 电介质层具有相同的光学厚度，并且通常具有相同的材料。 涂层的多层结构使得入射电磁辐射（其中半波长的奇数倍对应于入射波长处的多层涂层的光学厚度）不会在涂层内传播，并且在这些波长处的反射被抑制。 因此，可以将涂层设计成在可见波长光谱中具有接近成色的颜色。 反射层可以是金属或导电氧化物，导电氮化物，导电硅化物或导电硫化物。 吸收层可以是Cr，V，Pd，Ni，Pt，导电氧化物或亚化学计量的金属氧化物，如TiOx。 在使用非金属吸收体的涂层的一种形式中，第二介电层可以在至少一个多层堆叠中去除。 涂层可以结合在用于验证物品的真实性的系统中。
