Exosens currently operates an extensive industrial base spread across eleven production and research sites in Europe and North America. This geographic footprint enables the group to combine technological innovation with large-scale manufacturing capacity, addressing complex needs in sectors where the performance of optical systems is decisive. Its production lines integrate advanced processes for the development of image intensifier tubes, high-performance cameras, and particle and radiation detectors. The company also invests consistently in research and development, which allows it to remain at the forefront of optronics while delivering solutions adapted to highly demanding environments, whether for military operations, industrial control, or scientific research.

The acquisition of Phasics represents a strategic addition to this framework, bringing complementary expertise in optical metrology and laser beam analysis. With its patented QuadriWave Lateral Shearing Interferometry (QWLSI) technology, Phasics can accurately measure defects in optical components and characterize complex laser beams, enabling applications in high-resolution microscopy, optical communications, and the development of space and defense systems. Integrating this expertise within Exosens strengthens the group’s value chain by linking proven production capabilities with innovative metrology tools, facilitating the development of new instruments as well as quality control in its own manufacturing processes.

For Exosens, the contribution of Phasics goes beyond technology alone. By joining a group with an established international industrial presence, Phasics will be able to broaden the reach of its solutions, which until now have been focused on scientific and industrial niches, while benefiting from Exosens’ commercial network and resources. This complementarity translates into the possibility of designing integrated systems that combine high-performance imaging, advanced detection, and precision optical metrology. In a market where demand for turnkey and versatile solutions is growing, this integration opens the way to a differentiated offering likely to attract major research laboratories as well as aerospace, microelectronics, and space industries.

According to Jérôme Cerisier, Chief Executive Officer of Exosens, the integration of Phasics will strengthen the group’s multi-sensor approach and add new functionalities to its imaging solutions. This strategic direction is intended to keep the company at the forefront of optical technologies while reinforcing its position in demanding segments such as microscopy and free-space optical communications. For her part, Marie-Begona Lebrun, Chief Executive Officer of Phasics, emphasized that this merger represents an opportunity for international growth and for broadening the company’s overall offering, supported by Exosens’ industrial and commercial resources.

With more than 1,800 employees and a presence in highly specialized markets, Exosens has established itself as a key actor in global optronics. Listed on Euronext Paris and included in several benchmark indices, the company combines long-standing experience in technological innovation with a strategy of targeted acquisitions aimed at strengthening competitiveness. The integration of Phasics confirms this trajectory, adding new expertise to support the development of advanced optical solutions and accelerate innovation.

This transaction reflects Exosens’ objective of expanding its scope by combining industrial capabilities with advanced optical metrology technologies. It opens new perspectives for the development of integrated, high-value-added systems while providing Phasics with a platform to increase its visibility and international reach. In a sector where precision and performance are decisive, this acquisition marks an important step in consolidating French and European expertise in optronics and scientific and industrial imaging.
