January 20, 2026 – Sydor Optics, a U.S.-based manufacturer of precision optical components, announced its involvement in supporting the ITER (International Thermonuclear Experimental Reactor) program through the supply of test samples and optical windows for tokamak and its diagnostic systems.
ITER is one of the world’s most ambitious scientific collaborations, bringing together more than 30 nations to demonstrate the feasibility of fusion as a large-scale, carbonfree energy source. Optical components used within and around the tokamak must meet exceptional requirements for precision, material quality and manufacturing consistency.
Sydor Optics is providing custom flat optical elements manufactured and qualified to customer specifications using controlled polishing processes and comprehensive metrology. These components support optical and diagnostic subsystems critical to ITER’s research objectives.
“Participating in the ITER program reflects our strength in delivering precision optical windows for some of the most demanding scientific and energy applications around the globe,” said Matthew Sydor, President of Sydor Optics. “Our team is proud to contribute manufacturing expertise that supports advanced fusion research.”
Sydor Optics’ involvement underscores the company’s growing role in next-generation energy, scientific research, and high-reliability technology programs worldwide.
About ITER
ITER is an international nuclear fusion research and engineering project designed to demonstrate the scientific and technological feasibility of fusion power. The ITER tokamak, under construction in southern France, will be the world’s largest magnetic confinement fusion experiment.
