Fabrication and characterization of filters for the Large Synoptic Survey Telescope

摘要

The optical filters for the LSST, at about 760 mm diameter, are the largest precision optical filters we at Materion have ever fabricated. These six wideband interference filters on fused silica substrates: u, g, r, I, z, y, will enable this instrument. We present our results of the fabrication and characterization of these challenging optical interference filters.
