Dynasil History of Innovation

Dynasil's companies have been on the cutting edge of scintillation, optics, photonics, and material science for 140 years. Here are some of our most exciting innovations:

  1. 2018

    RMD Launches CLLBC Scintillator Technology

    RMD launches CLLBC (Cs2LiLa(Br,Cl)6:Ce) scintillator technology, a practical gamma-neutron detector for use as a replacement for both high energy resolution gamma-ray detectors and high pressure Helium-3 tubes for neutron detection.


  2. 2018

    A Technology Breakthrough Featuring a State-of-the-Art DLC Coating Chamber

    Using highly precise next-generation techniques, Dynasil has designed a DLC system that makes pinholes, the Achilles heel of optical coatings, virtually non-existent. We eliminated the 4 most common customer issues – pinholes, uniformity, stress and adhesion.

    Hilger Crystals’ Arrays Enable State of the Art Baggage Scanners

    Hilger Crystals supplies synthetic crystal arrays for state of the art, high speed baggage scanners.

  4. 2013

    Xcede Invents First Hemostat for Severe Bleeding

    Dynasil spins off Xcede Technologies to commercialize the first hemostat and tissue sealant capable of stopping severe and traumatic bleeding. This technology was originally developed within Dynasil Biomedical.

  5. 2013

    RMD Develops CLYC Crystals

    In response to the Helium 3 shortage, RMD develops CLYC scintillation crystals consisting of the elements cesium, lithium, yttrium, and chlorine, doped with cerium and with the lithium enriched in 6 Li. When utilized in a radiation detector, CLYC gives first responders the ability to identify the presence and type of nuclear radiation.

  6. 2012

    Optometrics Invents Combination Optical Grating & Filter

    In response to a customer need, Optometrics invents a combination optical grating and filter that simplifies manufacturing and creates a more robust product.

  7. 2010

    EMF Introduces Dichroic Coatings on Flexible Substrates for Lighting and Entertainment

  8. 2006

    RMD Invents 100,000 Frames/Second X-Ray Imaging

    RMD developed for the Department of Defense an ultra-high-speed, high-resolution, digital X-ray imaging system capable of acquiring images at a rate of 100,000 frames/ second. The system is based on a fast-decay scintillator screen coupled to an ultra-fast CCD camera designed for ballistic impact studies. A specially designed X-ray source provides blur-free images of hypervelocity projectiles traveling over 18,000 miles per hour.

  9. 1992

    RMD Develops Lead Paint Analyzer

    RMD introduces LPA-1, a portable X Ray fluorescence system for lead paint analysis, one of the most successful lead testing instruments ever developed.

  10. 1983

    RMD Invents Large Area Avalanche Photodiodes

    RMD invents Large Area Avalanche Photodiodes which greatly improve upon the signal to noise ratio of existing technology and are used in medicine and research.

  11. 1975

    Hilger Crystals Supplies Sodium Iodide Crystals for the EMI Scanner CT5000

    The EMI Scanner CT5000, was the first commercially available computed tomography (CT) whole body scanner. It was developed by Sir Godfrey Hounsfield. Hilger supplied the synthetic crystals for the scanner which made the first CT images of the human brain.

  12. 1974

    Radiation Monitoring Devices Inc. (RMD) Founded

    RMD eddy current technology awarded DOE development grants.

    RMD was founded by Dr. Gerald Entine to manufacture CdTe radiation detectors for use in nuclear power plants, medicine, and research.

  13. 1969

    Dynasil Fused Silica provides docking lights for Apollo 11

    Dynasil Fused Silica provides the docking lights for Apollo 11, the first manned mission to the moon.

  14. 1965

    Optometrics Founded

    Optometrics was founded as World Optics, Inc. by Mr. Peter Cianci in Waltham, MA.  They were primarily engaged in the manufacture of optical elements such as mirrors, lenses, prisms and windows.

  15. 1960

    Dynasil Fused Silica Launched with Space Program


    Dynasil Fused Silica was founded to provide synthetic fused silica for military radar applications. Dynasil gained national recognition as NASA acknowledged the capability of Dynasil grade fused silica to withstand the thermal shock and radiation effects of deep space. As the aerospace and laser optics industries exploded on the scene in the 1970’s, so did Dynasil.

  16. 1950

    Hilger Crystals Develops X-ray Detection Crystals for British Government

    Hilger was awarded the contract to develop X-ray detection crystals for the British Government. By 1968, the company was specializing in emission spectroscopy and crystals.

  17. 1936

    EMF Founded

    EMF was founded by a Cornell alumnus as the first company in the United States to provide evaporated metal thin film coatings.

  18. 1874

    Hilger Crystals Founded

    Hilger was founded by Adam and Otto Hilger to manufacture precision optical and mechanical instruments. Manufacturing was set up in London with a few employees who specialized in the manufacture of precision optical and mechanical instruments.
