Building out on work undertaken at the University Michigan, H3D specializes in highest-performance imaging spectrometers. The firm's lead product, called the Polaris-H, is a gamma-ray camera capable of identifying the source and isotope emitting gamma rays. prototypes in 2012, introduced commercially in late 2013 and deployed at nuclear plants around the US, including at the Fermi 2 and Cook nuclear facilities. The energy resolution of the Polaris-H is near 1% FWHM at 662 keV and the detector can localize gamma-ray sources in all directions simultaneously. Ready to use within two minutes of pressing the power button, the unit is airtight and watertight for easy decontamination.
