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 three companies — Dynasil Fused Silica, Hilger Crystals, and Radiation Monitoring Devices (RMD). We are a global supplier of fused silica and scintillation and detection solutions. We are also recognized experts in radiation detection, high-speed imaging, nuclear instrumentation, and non-destructive testing.


Dynasil has three facilities across Massachusetts, New Jersey, and Kent (UK) that, combined, provide nearly 100,000 sq. ft. of manufacturing space dedicated to helping our customers succeed — from prototype development to high-volume commercial production. At Dynasil, we embrace the spirit of continual improvement with many of our facilities achieving, and maintaining, ISO 9001:2015 compliance.

Hilger Crystals is the first of all Dynasil subsidiaries to meet accreditation of the three integrated management systems standards — ISO 9001 (quality management), ISO 14001 (environmental sustainability), and ISO 45001 (occupational health and safety.)

Our 175-strong workforce includes researchers, scientists, and design and manufacturing engineers who bring innovative technologies and solutions to market through close customer collaboration and committed back-office staff that keep each of the businesses running efficiently. Our customer base is just as diverse as our businesses, and spans 60 countries advancing industries including defense, security, academic and clinical research, semiconductors, utilities, aerospace, medical, and telecom. Because many of our products are used in US defense and space applications, several of our facilities adhere to ITAR compliance.
