In Troy, New York, Precision Manufacturing and Equipment Inc. designs and machines precision optics and components while handling the software and metrology in-house. Its work includes the protective optics used directly in the path of every National Ignition Facility fusion shot; after identifying their failure mechanism in 2003, PME developed a process that was adopted by France’s CEA fusion program. The company also builds browser-based tools for optical designers and metrologists, carrying its design-to-part approach beyond the machine shop.
