Thin Film Optical Coating Solutions

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 offer complete supply chain solutions for customers looking for a one-stop coating solution. EMF has been specializing in thin film coating technology and optical coating innovations for over 80 years. Founded in 1936 as the first thin film coating company in the United States, EMF collaborates with companies on product concept, design, engineering and build-to-print.

Custom Precision Optical Coatings

EMF offers an innovative portfolio of custom precision and high-volume coatings for a wide range of industries including automotive, defense, consumer electronics, dentistry, astronomy, utilities, lighting and entertainment. Twenty-six vacuum coating chambers offer 40 million square inches of coating capacity, enabling high volume production. Volumes can exceed millions of units annually, depending on the application.

Coatings can be applied to glass, metals, ceramics, plastics, and including IR optics such as germanium, zinc sulfide, zinc selenide, and chalcogenides.

Large Format and High Volume Coatings

2.5m Large Format Ball Aerospace Telescope MIrrorEMF operates twenty-six vacuum coating chambers and can handle large-scale optics up to 108” (2.75 m) in diameter with a weight up to 5,000 lbs (2,270 kg). Applications for these large scale coatings include flight simulator mirrors and astronomical mirrors.

When Electro Optic Systems (EOS), an Australian defense and space company, needed a precision aluminum coating for a very large telescope mirror, they came to EMF. Leveraging its deep expertise in highly-specialized optical coatings and highly-skilled, highly-knowledgeable coatings experts, EMF successfully coated the telescope mirror in 4 days.
