Zygo Corp., a Middlefield, Conn.-based optical metrology supplier, said its optical systems division has been awarded a $4.4 million contract to produce long-range night vision surveillance systems for a variety of Homeland Security, Department of Defense and Department of Energy applications. John Stack, president of the division, said, "Given the ongoing difficulty of protecting the world's shipping ports, nuclear reactors, air transportation systems, and borders, this opportunity fits well with the division's strategy to provide cost-effective manufacturing and design services to the high precision medical, defense, and commercial markets." The systems will be built in the company's Tucson, Ariz., plant, which specializes in high-precision optomechanical and electro-optical assemblies, using testing systems developed in Zygo's Costa Mesa, Calif., development center.For more information, visit: www.zygo.com
