BOSTON — RaySecur, a provider of real-time 4D Terahertz (T-ray) imaging for concealed threat and contraband detection, has announced significant market momentum and investment from IQT, a strategic investor for the U.S. national security community.
The IQT investment comes on the heels of a breakthrough year for RaySecur, beginning with the launch of the MS400, the world's first commercial 400 GHz T-ray security imaging system. Powered by RaySecur's proprietary T-ray technology platform, the MS400 delivers live-video security screening in both desktop and mobile battery-powered systems, is 10X smaller and 300X more sensitive than X-ray to detect low-density threats (powders, liquids, and laced-materials) and does not generate harmful ionizing radiation.
Rising security risks are driving strong demand for RaySecur's T-ray screening technologies to detect concealed threats and smuggled contraband that evade conventional methods. Leveraging the commercial success of the MS400, and aligned with the company' product expansion strategy, RaySecur announced a strategic investment from IQT, which RaySecur said reflects the growing importance of real-time, non-ionizing T-ray detection for uncovering concealed threats and contraband.
"IQT's strategic investment comes at a key inflection point in RaySecur's growth trajectory, building on the commercial success of our existing T-ray imaging platform and accelerating development of new dual-use product-lines directly aligned with our mission to deliver safe, accessible, and effective threat detection capabilities for high-security environments," says Alex Sappok, Ph.D., CEO, RaySecur.
The investment is expected to accelerate RaySecur's innovation and expand dual-use commercial reach of its advanced detection technologies across government, public safety, and corporate enterprise markets.
"We are pleased to welcome RaySecur to the IQT portfolio," says Jon Chait, Managing Partner, IQT. "Their 4D T-ray imaging technology represents an important innovation in security detection, enabling real-time, safe, non-ionizing screening for concealed threats and contraband. RaySecur's track record of focusing on operational simplicity, safety, and detection performance aligns with IQT's mission to accelerate impactful commercial technology for the U.S. national security community."
