Duryea, PA--Schott has opened a new optical-coating facility at its manufacturing site in Duryea; the new facility houses chambers for antireflective (AR) and highly reflective (HR) coatings of polished filters and components of up to 14 in² or 18 in. diameter in size for the visible and near-IR spectral ranges.

Schott invested $2 million in the new facility to expand its coating capabilities for the United States defense industry. The facility covers more than 2,000 square feet and contains coating chambers of different sizes. The company will use e-beam and ion-assisted e-beam evaporation technologies to ensure that coated components meet the reflection and environmental specifications set by the International Organization for Standardization (ISO), American National Standards Institute (ANSI), and the military (e.g. MIL-C-675, MIL-C-14806A).

The Duryea facility manufactures optical glass and finished components for applications that include contrast-enhancement filters for aircraft displays, active laser glasses for high-energy lasers, laser rangefinders, and Zerodur for space applications.
