Large Synoptic Survey Telescope
LSST Secondary Optic and Cell Assembly
As part of the National Science Foundation (NSF) led LSST project team, L3Harris will provide both the secondary mirror and mirror cell assembly for the ground-based telescope located on Cerro Pachón in Chile. During its operation lifetime of 10 years, LSST will detect tens of billions of objects, allowing it to chart the history of the expansion of the dynamic universe. The telescope will also support the research areas of dark matter and energy.
LSST’s 3.5-meter diameter secondary mirror is a solid meniscus design fabricated from ultra-low expansion glass. L3Harris is also responsible for manufacturing LSST’s cell assembly, which includes the polished secondary mirror, mirror support system, mirror cell electronics and sensors, thermal control system, and mirror control system.
As one of this century’s most exciting astronomy projects, LSST has been designated as a public facility. With this designation, the data products will be made available to all quickly over the internet.
