The AOS is a precision beryllium rectangular optical bench that houses the tertiary and the fine steering mirror installed at the center of Webb's primary mirror. The AOS is surrounded by a shroud that eliminates stray light, and two large radiator panels that keep the assembly cold. This subsystem collects and focuses the light from the secondary mirror and feeds it into the science instruments.", "items": [], "extra_data": {} }, { "id": 334286, "url": "https://svs.gsfc.nasa.gov/12213/#media_group_334286", "widget": "Basic text", "title": "For More Information", "caption": "", "description": "See [NASA.gov](http://www.nasa.gov/mission_pages/webb/news/aft-optics.html)", "items": [], "extra_data": {} } ], "studio": "GMS", "funding_sources": [ "ESE" ], "credits": [ { "role": "Producer", "people": [ { "name": "Nasreen Alkhateeb", "employer": "Advocates in Manpower Management, Inc." }, { "name": "Michael McClare", "employer": "HTSI" } ] }, { "role": "Cinematographer", "people": [ { "name": "Nasreen Alkhateeb", "employer": "Advocates in Manpower Management, Inc." } ] }, { "role": "Editor", "people": [ { "name": "Nasreen Alkhateeb", "employer": "Advocates in Manpower Management, Inc." }, { "name": "Michael P.
