Canada-France-Hawaii Telescope (CFHT) and Gemini Observatory have awarded Rockwell Scientific Co. LLC two $2.2 million contracts to produce molecular beam epitaxy mercury cadmium telluride 2048 X 2048 short-wave IR sensor chip assemblies on Rockwell's Hawaii-2RG multiplexers. Sets of four focal plane arrays will be tiled into 2 X 2 mosaics totaling 4096 X 4096 pixels. One mosaic will be installed in the CFHT wide-field infrared camera on Mauna Kea, Hawaii, and the other in the adaptive optics near-infrared imager on Gemini South in Cerro Pachón, Chile. Both are used in ground-based astronomy applications.
