Dynasil

What Dynasil does

Dynasil Corporation of America is a US-headquartered, multinational photonics and materials science company that develops and manufactures precision optical components, scintillation crystals, radiation detection systems, and infrared optical coatings. Founded in 1960 and currently operating through wholly-owned subsidiaries Hilger Crystals (UK-based synthetic crystal manufacturer with capacity of ~2,000 kg/month) and Radiation Monitoring Devices/RMD (radiation detection, high-speed imaging, and non-destructive testing), the company also owns EMF Corporation and Optometrics Corporation for infrared HEAR/DLC thin-film coatings, and majority-owned Xcede Technologies for hemostatic surgical patches. Core technologies include CLYC scintillation crystals, phase-change metasurfaces for infrared, proprietary dual-mode radiation detection, and ISO 9001:2015 / ITAR-compliant manufacturing across facilities in Massachusetts, New Jersey, and Kent (UK).

The company's revenue model is dual-track: hardware sales of optics, scintillation crystals, fused silica, and infrared coatings (FY2016 Optics revenue $23.7M at 34% gross margin) combined with US government R&D contract services (FY2016 Contract Research $19.8M at 38% gross margin). It serves defense/homeland security, medical, industrial inspection, semiconductors/solar, and academic research end-markets across roughly 60 countries via direct enterprise sales, an e-commerce catalog for standard products, and channel partnerships (notably Militram Futuristic Technologies for Israel, providing access to US FMF/FMS congressional funding). The company was listed on NASDAQ until August 2019, when it terminated SEC registration and now trades on the OTC Pink Market; in late 2022, Dynasil repurchased approximately 47% of its outstanding shares at $2.49/share for ~$17.4M.

Core offering

Dynasil develops and manufactures precision optical crystals, scintillation crystals, radiation detection systems, infrared optical coatings, and fused silica components through its subsidiaries Hilger Crystals and Radiation Monitoring Devices (RMD). The company also provides contract R&D services in radiation detection and materials science primarily to US government agencies, and has developed the Xcede resorbable hemostatic patch through its subsidiary Xcede Technologies for surgical bleeding control.

Product overview

Dynasil is a multinational photonics and materials science company that develops and manufactures optical materials, scintillation crystals, radiation detection systems, and optical coatings. The company operates through two primary subsidiaries - Hilger Crystals (optical crystals for spectroscopy and scintillation) and Radiation Monitoring Devices/RMD (radiation detection and imaging systems). Additional subsidiaries include EMF Corporation (optical coatings including HEAR and DLC coatings), Optometrics Corporation (optical components), and formerly Xcede Technologies (hemostatic patches). The product portfolio spans synthetic crystal growth, radiation detectors packaged with SiPMs/CCDs/PMTs, infrared optical coatings, and medical device components.

Functional benefit

Products and services

• CLYC Scintillation Crystal Cesium Lithium Yttrium Chloride (CLYC) scintillation crystal used in radiation detection applications, including spectroscopic personal radiation detectors, that achieves hemostasis-relevant accuracy and precision benefits for homeland security and scientific instrumentation customers.
• Xcede Patch Resorbable hemostatic patch designed to stop surgical bleeding (hemostasis) within 60 seconds, faster than approved alternatives taking approximately three minutes. Targets severe, traumatic bleeding and surgical applications including liver resection. Developed by majority-owned subsidiary Xcede Technologies.
• Dynasil Fused Silica (DFS) Fused silica products and components for photonics applications, used by semiconductor manufacturers, solar energy producers, and other optics customers globally.
• Infrared HEAR and DLC Optical Coatings Infrared High Efficiency Anti-Reflective (HEAR) thin film coatings achieving less than 0.3% average reflection for the 8-12 micron spectral region, plus Diamond Like Carbon (DLC) coatings that pass sand-water slurry wiper tests for air, ground and sea applications. Sold to military, homeland security and commercial IR optical system integrators.
• Contract Research Services (Radiation Detection and Materials Science) R&D contract research services in radiation detection, scintillation materials, and materials science, primarily for U.S. government agencies including the Department of Homeland Security, U.S. Air Force, and National Science Foundation. Includes development of next-generation scintillators and radiation detection capabilities.
