First Glimpse of Fused LSST M2 Substrate at Corning

Thursday, March 19, 2009

Quality Assurance Technician Brian Todd unveils the LSST secondary (M2) mirror substrate recently fused at Corning's Canton, NY, facility. After inspection and removal from the furnace, Corning will grind the 3.5-meter annulus and then return it to the oven for a controlled melt which helps define the final shape of the 100mm (3.9-inch) thick meniscus substrate. Delivery to the LSST Project is planned by the end of 2009.

Financial support for Rubin Observatory comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded Rubin Observatory Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA).  The DOE-funded effort to build the Rubin Observatory LSST Camera (LSSTCam) is managed by the SLAC National Accelerator Laboratory (SLAC).
The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future.
NSF and DOE will continue to support Rubin Observatory in its Operations phase. They will also provide support for scientific research with LSST data.
