6 August 2010 Super hardpoints for the Large Binocular Telescope
Author Affiliations +
We describe the design and performance of an improved hardpoint for the primary mirror cell of the Large Binocular Telescope. Six hardpoints define the position and orientation of the primary mirror and are key elements of the active optics system. After several years of operation, various undesirable characteristics of the original hardpoints were identified. A new deign was developed that provides higher stiffness, greater repeatability, and better overall performance. We describe the design features and present preliminary performance data from lab testing and initial operation in the telescope.
