A collaborative project between the University of Poitiers (P‘Prime) and the company SAGEM, which is the subject of two separate ERDF files. The P’Prime institute applies and transfers its research to SAGEM on the optimisation of optonic devices (optical and electronic) in particular on integrated detection and security systems including sensors, intelligent optics and multifunctional devices. The improvement axes concern the lens as well as the treatment of optics, especially for anti-reflective properties, demisting, hydrophobicity that can be applied to binoculars, shooting glasses, infrared detectors...
