G-S Plastic Optics Opens In-House Coating Facility

Oct 2006
G-S Plastic Optics (G-SPO) of Rochester, N.Y., announces the completion of its most recent plant expansion through the establishment of an in-house coating facility with technology specific to polymer substrates. In April, the company integrated a precision optical coating system, built by Vacuum Process Technology Inc., that includes e-beam and resistive evaporation with plasma ion assist to form low stress, dense and durable coatings that meet the thin-film requirements of polymer optics. The facility has in-house metrology, including reflection and transmission measurement capability on both PerkinElmer Lambda 650 and Lambda 10 UV-Vis-NIR spectrophotometers and other film characterization resources. G-SPO said it will focus on providing vacuum-deposited coatings on polymer substrates such as PMMA, styrene, polycarbonate, Zeonex, Zeonor and Topas.
