Murrieta, California, July 28, 2009 - Exotic Electro-Optics, Inc. (EEO), a subsidiary of II- VI Incorporated (NASDAQ Global Select: IIVI), announced today that EEO has entered into an exclusive teaming agreement with Composite Mirror Applications (CMA), a Tucson, AZ based producer of high quality, lightweight and thermally stable mirrors and structures in carbon fiber reinforced composite (CFRP) materials. CMA and EEO plan to pursue potential markets in optical systems and components for tactical military, aerospace and commercial applications. The combination of CMA’s proven CFRP precision optical replication technology and EEO’s design for manufacturability engineering experience will serve several markets driven by low mass, high thermal stability and high optical performance requirements. An opto-mechanical assembly is currently being jointly developed to demonstrate the feasibility of a production ready composite based architecture; details on this assembly will be released at a later date.
