Your library or personal account may give you access

Abstract

The 1.2 m secondary mirror for the Sloan Digital Sky Survey Telescope (SDSS) is the first mirror to be fabricated using a new process and facility at the Steward Observatory Mirror Lab. We write this summary during the loose-abrasive grinding stage, which is guided by mechanical profilometry. At the meeting we will present the status of polishing and optical testing.
