Thin, unbacked, aluminum film filters were used on two extreme ultraviolet (XUV) instruments flown on the Apollo Telescope Mount of Skylab by the Naval Research Laboratory to transmit the XUV radiation while blocking the longer wavelength radiation that would saturate the detector. The requirements placed on these filters-large size, resistance to degradation by high acoustic and vibration fields, and low pinhole transmittances-were far more severe than those placed on any filters previously flown. Special techniques were developed for vacuum evaporation of the aluminum, removal of the films from the substrates, supporting the films and mounting them to obtain finished filters, and storing them so that no degradation took place. A description of these techniques will be given.
美国海军研究实验室在“天空实验室”的阿波罗望远镜支架上搭载的两台极紫外（XUV）仪器上使用了薄的、无衬背的铝膜滤光片，以传输极紫外辐射，同时阻挡会使探测器饱和的较长波长辐射。对这些滤光片的要求——大尺寸、耐高声学和振动场降解以及低针孔透过率——比以往任何飞行过的滤光片的要求都要严格得多。为铝的真空蒸发、从基板上取下薄膜、支撑薄膜并将其安装以获得成品滤光片以及储存它们以避免降解，开发了特殊技术。将对这些技术进行描述。
