Abstract

Latest progress on Tinsley methods are described for faster stress mirror polishing (SMP) of the Thirty Meter Telescope (TMT) primary mirror segments as well as the European Extremely Large Telescope (EELT). Most recent data is shown which illustrates that the SMP process is capable of producing very smooth surfaces to 1um PV, independent of the segment type being produced.
