June 2011: Delivery of three of six 500mm Gas-Fusion flats to L-3 Communications Tinsley in six weeks.
February 2011: Delivery of final ARGOS mirror blank to the Large Binocular Telescope. The 650mm x 550mm mirror blanks are to be finished by Zygo Corporation as part of a guide star adaptive optics system for the telescope.
December 2010: Delivery of light weight 1.25 meter primary and 450mm secondary mirror blanks to San Diego State University for telescope upgrade project. The blanks were delivered to NuTek for final finishing.
August 2010: Hextek Corporation delivers the final ACF (auto collimation flat) to ITT Geospatial Systems in Rochester, NY for the James Webb Space Telescope program. A total of four flats have been shipped for use in testing the JWST primary mirror segments. The mirrors will be used to test the alignment system of the telescope at the Johnson Space Flight Center prior to launch. During the test, the mirrors will see near space conditions under vacuum at about 32° K. Three mirrors will be used simultaneously; suspended above the JWST mirror segments. The combination of the substrate’s robust nature, light weight and near zero coefficient of thermal expansion at cryo-temperatures made the Gas-Fusion mirror the ideal choice for this demanding test.
