MURRIETA, CA., September, 3, 2009 – Exotic Electro-Optics, Inc. (EEO), a subsidiary of II-VI Incorporated (NASDAQ Global Select: IIVI), broke ground today on a new facility next to its primary manufacturing operations in Murrieta, California that will support large sapphire window fabrication used on programs for Intelligence, Surveillance and Reconnaissance (ISR) applications. This facility is targeting to be fully operational in the next 12 months.

The 24,000 square foot facility was designed with Lean manufacturing principles and will increase EEO’s capacity for large sapphire window fabrication by 400%.

Local and Federal Government dignitaries participated in the groundbreaking ceremony, including: City of Murrieta Council Member Randon Lane, City of Temecula Mayor Maryann Edwards and Rep. Mary Bono Mack, U.S. House of Representatives, 45th District.

"This expansion signifies Exotic Electro-Optics long-term commitment to the ISR market and the community" said EEO General Manager Mark Maiberger. "Our sapphire business alone has created 15 additional jobs in the community over the last 5 years and will create 50-75 more highly skilled engineering and technical positions in the coming years."

“This is an exciting expansion of a local business that will bring new jobs and new opportunities to our community,” said Bono Mack. “Exotic Electro-Optics is an innovative and dynamic company that is using new technologies to transform our defense capabilities and enhance our national security, and in the process, it provides hundreds of jobs for our community and contributes significantly to our local economy. I am honored to celebrate this ground-breaking with so many members of our community, and I look forward to the continued growth and advancement of this outstanding company that is offering so many benefits to both our region and our nation.”

This facility expansion is adjacent to EEO’s existing 62,000 square foot facility which provides optics and optical assemblies for visible through infrared applications in the ISR market for terrestrial, airborne, space and un-manned systems.
