Abstract: Reflective polarizers, which transmit one polarization and reflect the other polarization, have an extended red band edge in the off-axis transmission spectrum to control off axis color (OAC) hue. To control the OAC hue, the red band edge of the off-axis transmission spectrum, or OAC spectrum, is shifted beyond the boundary for red light, or to at least 600 nm. Even more preferably, the OAC spectrum is extended further into the red than any red emission peak of an associated lamp providing light into a system in which the reflective polarizer is used. The concept applies equally well to any type of reflective polarizer, such as multilayer reflective polarizers, cholesteric reflective polarizers, and the like. The resulting reflective polarizers are very useful for many different applications, such as liquid crystal displays.

Abstract: An elevated walkway support system comprising a plurality of horizontal support members supporting said walkway above a foundation, the horizontal support members adapted for attachment at first ends thereof to one or more associated supports; and a plurality of adjustable length braces extending between second ends of respective ones of the horizontal support members and the foundation at a location closer to the first ends than the second ends in a horizontal direction.
