    Abstract: A combination of filters for filtering selected wavelengths of electromagnetic radiation is provided on a transparent substrate such as a plastic film or glazing of a window. The combination of filters prevents or attenuates the passage of wavelengths through the substrate which would pose a security risk. The combination of filters is useful to prevent unauthorized data collection and information exchange from or within buildings or otherwise prevent such unauthorized data collection and information exchange from, for example, computer monitors or screens, personal digital assistance, and local area networks. The substrate with the combination of filters may be in the form of a bag or a tent.

    Abstract: A heat reflecting fenestration composite is provided which includes in sequence: (a) a substantially transparent substrate; (b) a first outer dielectric layer; (c) an infrared reflecting metal layer; (d) a color correcting metal layer comprising a metal different from the infrared reflecting metal layer; (e) a protective metal layer comprising a metal different from the infrared reflecting metal layer and different from the color correcting layer; and (f) a second outer dielectric layer. The dielectric layers are typically indium oxide, indium zinc oxide, indium tin oxide or mixtures thereof. Preferably, the composite also includes additional layers of infrared reflecting metal layer, color correcting metal, protective metal and dielectric. Also preferably, the composite comprises a top layer of glass or transparent polymeric plastic. The infrared reflecting metal layer is typically silver, gold, copper or alloys thereof. The color correcting metal layer typically has a refractive index in the visible light range between about 0.6 and about 4 and has an extinction coefficient for light in the visible light range between about 1.5 and about 7. Metals such as chromium, cobalt, nickel, zinc, palladium, indium, tin, antimony, platinum, bismuth and alloys thereof can be used in the color correcting metal layer, with indium being preferred. The protective metal layer is made from a metal whose oxide is substantially non-optically absorbing, such as aluminum, titanium, zirconium, niobium, hafnium, tantalum, tungsten and alloys thereof, with titanium being preferred. The color correcting and protective metal layers can also be disposed on both sides of the infrared reflecting metal layer. Such composites provide a heat reflecting fenestration structure having exception degradation resistant properties and visible light transmission reduction properties, without excessive reflectance.
