Exosens S.A. (formerly Photonis Group) designs, develops, and manufactures high-performance electro-optical components, sensors, and imaging subsystems. The company operates primarily through two segments: Amplification and Detection & Imaging. Amplification (generating roughly 68% of 2025 revenue) focuses on electron and light amplification devices, most notably image intensifier tubes used in military night-vision goggles, weapon sights, and vehicle-mounted surveillance systems. Detection & Imaging (accounting for roughly 32% of 2025 revenue) offers specialized digital cameras, hyperspectral imaging instruments, neutron and gamma radiation detectors, wavefront sensors, and ion detectors for analytical instrumentation and nuclear reactors.
By end market, Defense & Surveillance represents the company's largest demand driver, generating approximately 75% of group revenue in 2025, supported by surging demand for advanced night vision, drone/counter-drone electro-optics, and border security. The remaining 25% is diversified across civil nuclear energy (including small modular reactors), life sciences instrumentation, and industrial inspection. Geographically, Exosens sells worldwide, with major revenues generated across Europe, North America, and Asia-Pacific. The company maintains 12 manufacturing and development sites across France, the Netherlands, Belgium, Germany, the United Kingdom, the United States, and Canada. Exosens maintains a commanding global competitive position in light intensification and defense photonics, characterized by high technological barriers to entry, strict regulatory export compliance, and proprietary manufacturing processes.
