Institut für Informationsverarbeitung (TNT) - Homepage of Konrad Bethmann

Konrad Bethmann studied physical technology with a focus on laser technology at the Mittweida University of Applied Sciences. After completing his diploma thesis at the Fraunhofer Institute IWS in Dresden, he studied physics at the TU Clausthal with a focus on applied photonics. After stadiums at the Fraunhofer HHI and the Hannover Medical School, Mr. Bethmann has been an employee of the AG Munderloh at TNT since December 2022.
