Lawrence Livermore National Laboratory ordered 192 vacuum relay telescopes from Zygo Corp. in Middlefield, Conn. The contract, including options, runs through 2007 and has a potential value of $7.66 million. Zygo will produce the components at its optical assembly center in Tucson, Ariz., and transfer them to Livermore, which plans to install them in its National Ignition Facility, designed for the study of nuclear weapons physics and controlled thermonuclear fusion.
