What H3D does

H3D, Inc. is a University of Michigan spinout founded in 2014 in Ann Arbor, Michigan, that designs, manufactures, and sells high-performance gamma-ray imaging spectrometers based on proprietary 3D position-sensitive Cadmium Zinc Telluride (CZT) semiconductor detector technology invented by Prof. Zhong He. The company leverages a patented voxel-by-voxel calibration architecture that eliminates the traditional resolution-versus-volume tradeoff in CZT detectors, achieving energy resolution better than 1% FWHM at 662 keV without cryogenic cooling. Its product portfolio spans the H Series (H100, H400, H420, H1600) imaging spectrometers, A Series handheld radioisotope identification devices, S Series industrial spectrometers, M Series OEM-integrable modules, P Series collimated spectrometers, T Series ruggedized modules, plus software add-ons (GammAware 3D mapping, GammaTrend remote monitoring, SourceTerm quantification) and specialty systems such as the J Series for proton-therapy imaging.

The company serves nuclear power plants, CBRNE and emergency-response agencies, defense and military customers (US DoD/DTRA, US Army, Swiss armasuisse), international safeguards bodies (IAEA), nuclear-waste handlers, and medical imaging researchers, with products used by over 75% of US nuclear power plants and distributed through a global channel network covering more than 25 countries. Revenue is generated primarily through one-time hardware sales of $100K+ instruments, complemented by software add-ons, calibration and training services, and extended warranties; distribution combines direct enterprise field sales with regional distributors providing local sales, demonstration, and support.

H3D is led by Dr. Willy Kaye (CEO, U-M PhD), Dr. Michael Streicher (COO/President, U-M PhD), Prof. Zhong He (Chairman, inventor of the underlying technology), Dr. Feng Zhang (CTO), and a team of approximately 11 PhD-level scientists and engineers, supported by an advisory board including the former Acting Director of the US Domestic Nuclear Detection Office. The company holds five granted US patents on its core technology, is ISO 9001 certified, and has received multiple Ann Arbor SPARK FastTrack awards, the 2020 Corporate Vision Small Business Award for room-temperature gamma-ray detection, and the 2023 World Nuclear Exhibition Products & Services Innovation Award for GammAware.
