Infrared Filters on the NASA LDEF
What is it about?
Infrared optical multilayer filters and materials were exposed to the space environment of low Earth orbit for a period of nearly six years on the NASA Long Duration Exposure Facility (LDEF) mission. This paper describes the effects of that environment on the physical and optical properties of filters and materials used in an experiment designed by the University of Reading Infrared Multilayer Laboratory.
Why is it important?
This experiment was to expose infrared multilayer interference filters of novel design, construction and manufacture for sensing atmospheric composition and temperature to space radiation. The optical behaviour of these filters when in space being unconfirmed previously, but crucial to their performance.
