Development of infrared materials for fibres, lenses and windows for harsh environment

许多航空航天应用需要使用可见光和红外系统。集成这类系统的趋势越来越大，而且需要在整个紫外到长波红外波段都透明的材料。除了光学透明度和光学质量外，材料在航空航天环境中的坚固性也很重要。它们需要承受高温、磨蚀环境和不同的湿度水平。合成满足这些要求的新材料将成为本研究的核心。窗户、透镜和纤维将各自具有不同的光学质量和物理尺寸组合，这可能会导致材料针对特定应用进行优化。这个项目将在实际工程限制下解决这种材料系统的潜力。这将使我们能够利用最先进的技术和设计可实现的平台。

A number of aerospace applications require the use of visible and infrared systems. There is an increasing trend for the integration of such systems and the need for materials that can be transparentacross the complete UV to long wave IR wavelengths. In addition to the optical transparency and optical quality it will be important that the materials are robust to an aerospace environment. They willneed to withstand high temperatures, abrasive environments and varying humidity levels. The synthesis of new materials to address these requirements will form the heart of this research. Windows, lenses and fibres will each have a different combination of optical quality and physical size which may lead to materials optimised for given applications. This project will address the potential of such material systems within practical engineering limitations. This will enable us to exploit state-of-the-art technologies and design realisable platforms.
