The IRSN – Institute for Radiological Protection and Nuclear Safety – is the French national public expert in nuclear and radiological risks. IRSN has nearly 1,750 employees made up of specialists, engineers, doctors, agronomists, veterinarians, technicians, experts and researchers. The Institute is placed under the joint supervision of the Minister of Ecological Transition, the Minister of the Armed Forces, and the Ministers responsible for Energy Transition, Research and Health.
As part of a chemiluminescence experiment of the OH molecule (production of light following a chemical reaction), Mr. Pretrel – research engineer, authorized to supervise research within IRSN – had to detect the UV light emanating from flames using an intensified camera. Its specifications required the installation of an UV window.
Mr. Pretrel selected the FMIR window from SOREM, a subsidiary of Wintech Groupe.
