SCHOTT North America Announces New U.S. Production Capability for Infrared Components
• SCHOTT Produces Chalcogenide Glass in the United States for the First Time
August 23, 2011 (at the SPIE Optics & Photonics Conference in San Diego, CA) – Today, SCHOTT North America (booth 611) announced the availability of chalcogenide glasses for infrared (IR) sensing. This new manufacturing line is based in Duryea, PA., marking the first time SCHOTT will produce chalcogenide glass components in the United States.
SCHOTT’s IG series of chalcogenide glasses is ideal for defense and security applications like night vision and thermal imaging. It provides high transmission quality across a wide range of the IR spectrum, from the near-infrared (NIR) to long-wavelength infrared (LWIR) regions. Like many of SCHOTT’s glasses for defense applications, chalcogenide glass has a broad transparency range and consistent optical behavior over a wide temperature range, assuring it can withstand extreme environments without defocusing. This is a key advantage over germanium in many IR applications.
The new chalcogenide glass melting, fabrication and metrology capabilities at the Duryea facility will provide customers with a family of IR glasses to meet customers’ specific requirements for their application. “SCHOTT is pleased to be able to offer a high quality, domestically produced source of chalcogenide glass components to serve our customers in the U.S. defense market," said Heather Rayle, Vice-President and General Manager for the North America Advanced Optics business. “The chalcogenide glasses are a cost-effective, high performance alternative to germanium in many IR optical designs requiring consistent performance across broad temperature ranges.”
