Founded in 1936, Evaporated Metal Films (EMF) was the first company in the US to offer thin film coatings. For over 80 years, EMF has continually expanded and refined its capabilities to deliver high performance optical coatings. EMF today offers an innovative portfolio of precision custom and high-volume coatings for a wide range of industries including automotive, defense, consumer electronics, dentistry, astronomy, utilities, lighting and entertainment.
Coatings can be applied to glass, metals, ceramics, plastics, and including IR optics such as germanium, zinc sulfide, zinc selenide, and chalcogenides. EMF provides optical coating solutions for plastic, glass, metal, and ceramics. It also manufactures industry-leading rhodium-coated dental mirrors for intra-oral photography under the Riofoto brand.
Throughout the years, EMF has expanded the breadth of their optical coating technology and capacity. In 1987, a 44,000 square foot facility was purpose-built to accommodate a growing customer base in automotive components, display systems, instrumentation, satellite communications, flexible substrates, protective face shields, power cell components, glass, and lighting. An additional 50,000 square foot facility was added in Rochester, NY in 2014 which significantly expanded the large chamber coating capabilities and capacity.
A custom-designed and purpose-built DLC coating chamber can coat IR optics such as silicon, germanium, zinc sulfide, zinc selenide, and chalcogenides.
