EMF can handle very large area and very high volume coating production. Our Rochester, NY facility has fourteen 96” (2.5 m) diameter coating chambers. Volumes can exceed millions of units annually, depending on the application. Please contact us to discuss your high volume coating needs.
An optical coating is one or more thin layers of material deposited on a substrate. Coatings change the way light is reflected or transmitted by the substrate. Dynasil provides optical coating services through EMF. Coatings can be deposited on customer supplied optical parts, as well as a broad range of substrates including glass, metal, ceramic, and plastic. We also offer complete supply chain solutions for customers looking for a one-stop shop. EMF has been specializing in thin film coating technology and technical innovations for over 80 years. Founded in 1936, EMF is the most established thin film coating company in the United States. EMF works with customers all the way from product concept to build-to-print and any point in between. We can manage the complete process from part production to finished coated part as needed.
