TNO and Demcon explore joint venture for deformable-mirror technology

10 July 2026

TNO and Demcon presented plans for a new joint venture focusing on advanced technology for deformable mirrors at the SPIE event in Copenhagen. The aim of the collaboration is to prepare this crucial Dutch technology for the global market by further developing specialised prototypes into a robust, commercially scalable product line. Both parties are aiming for a leading international position in growth markets such as astronomy, optical communications, laser systems and laser-induced nuclear fusion.

From laboratory technology to a commercial product

At the heart of the proposed collaboration is TNO’s patented hybrid variable reluctance (HVR) actuator technology. This technology delivers a significant increase in power output compared with existing systems, enabling the use of thicker and more durable mirrors. This resolves a major bottleneck: the fragility and high maintenance requirements that have hitherto limited this technology to laboratory applications. The result is a solution suitable for large-scale, global commercial application.

Arnaud de Jong, Managing Director of TNO High Tech Industry, points out that whilst developing groundbreaking technology is part of TNO’s core business, real impact is only achieved when that innovation is successfully scaled up for the market. Together with its long-standing partner Demcon, TNO aims to accelerate that transition from deep tech to a fully-fledged business.

Dennis Schipper, CEO of Demcon, emphasises that Demcon excels at translating complex technology into robust product ranges. Drawing on its expertise in mechatronics and industrialisation, the company aims to build a leading international market position in collaboration with TNO, thereby delivering reliable, standardised solutions for commercial applications worldwide.

Applications with a global impact

The proposed technology addresses key challenges in the infrastructure of the future. At a time when data security and connectivity are paramount, the technology enables ultra-fast and secure laser communication between Earth and space. It also offers astronomy unprecedentedly sharp observational capabilities for research into the universe. In this way, decades of research at TNO are translating into tangible economic value and societal impact.
