From its Harrisburg base, Applied Research & Photonics develops terahertz spectrometers and provides non-contact, non-destructive testing for semiconductor and nanomaterial research. Its TeraSpectra and TNS3DI systems combine spectroscopy with subsurface, layer-by-layer 3D imaging to locate defects within materials rather than only viewing their surfaces. The company’s work has received recognition including the 2011 CLEO/Laser Focus World Innovation Award and NASA Tech Briefs’ 2008 Nano-50 Innovator Award for founder and CTO Anis Rahman.
