The US Department of State has approved a technical assistance agreement (TAA) between Naked Optics Corp. (NOC) of North Branch, N.J., and Vitron GmbH of Jena, Germany. The TAA allows NOC to transmit government-restricted drawings to Vitron so the company can manufacture infrared materials, blanks and optical components from materials such as zinc sulphide, clear-grade zinc sulphide, calcium fluoride and chalcogenide glass. The TAA is in effect until Dec 31, 2015. NOC has a similar agreement with Phoenix Optical Glass Ltd. of St. Asaph, Wales, a manufacturer of optical glass blanks and diamond-turned components. That TAA is in effect until Dec. 31, 2013. NOC is the exclusive distributor for both Vitron and Phoenix Optical Glass in the US.
