Dynasil, a publicly-owned multinational corporation headquartered in the US, focuses on cutting-edge research and commercial product development in photonics. We serve our customer base through five companies — Dynasil Fused Silica, Evaporated Metal Films (EMF), Hilger Crystals, Optometrics, and Radiation Monitoring Devices, Inc. (RMD). We are a global supplier of fused silica, coatings, components, and scintillation and detection solutions. We are also recognized experts in radiation detection and imaging, nuclear instrumentation, and non-destructive testing.
With 26 vacuum coating chambers, capability to handle large-scale optics up to 108” (2.75m) and 5,000 lbs (2, 267 kg) and 80+ years of experience, EMF is uniquely capable of handling large format optics and special substrate programs that require intensive engineering interaction and careful program management. Applications for these large scale coatings include telescope mirrors, flight simulator mirrors and astronomical mirrors.
An ISO 9001:2015 certified global leader in optical materials, components and coatings. Dynasil is a recognized leader in optical materials, thin-film coatings and components i.e. wavelength selection solutions. We are also a global leader in radiation detection and imaging and known for our state-of-the-art scintillation and detection solutions.
A DLC coating is the preferred choice for IR optics that have to withstand harsh environmental conditions. It adheres to virtually all lR substrates - Ge, Si, ZnSe, ZnS, CaF2, sapphire, and chalcogenides. It is an Anti-Reflective (AR) coating with high hardness and good stress resilience with minor losses (between 5-10%) in transmission. Our proprietary "coat up" PE-CVD process virtually eliminates typical coating defects - pinholes, stress, uniformity and adhesion. Coatings adhere to MIL-M-13508C and MIL-C-675C standards for adhesion, abrasion, humidity, solubility, salt spray, temperature cycle and sand-slurry wiper.
Radiation Monitoring Devices, Inc. (RMD) is among the foremost experts in the fields of radiation detection and imaging, nuclear instrumentation, and non-destructive test equipment. Since 1974 RMD’s mission has been to conduct world-class research and develop industry-leading commercial products. Today, that mission in undertaken by more than 60 scientists and engineers who are more often shaping materials research and development rather than following it. With more than 70 awarded U.S. patents, RMD's research and products are utilized in a wide range of scientific fields, from space science to particle physics, and from nuclear security and safeguards to clinical diagnoses and environmental research.
Hilger Crystals is an ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certified company with a long-established history and proven reputation producing high-quality synthetic crystals for infrared spectroscopy and X and gamma ray detection. Products can be built to custom design requirements and supplied within short lead times.
EMF provides a full line of standard high-performance microscope test slides for corrosion testing, scanning probe and atomic force microscopy, Raman spectroscopy, micro arrays, cell culture and lab applications. Whether you’re a university researcher, an electronics fabricator or a medical technician our slides are guaranteed to exceed your performance requirements and expectations.
EMF, pioneer in optical coating solutions since 1936 was the first company in the United States to offer evaporated metal thin film coatings. Today, with its 26 vacuum coating chambers EMF offers 40 million sq. in. of coating capacity for high volume applications in automotive, displays, instrumentation, satellite communications, protective face shields, power cell components, glass, lighting and entertainment. And, its chambers are capable of large format optics up to 108" for land and space-based astronomy,
