- Hamamatsu Photonics K.K. (6965.T) manufactures and markets photonics products including photomultiplier tubes, imaging devices and image sensors, light sources such as lamps and LEDs, opto-semiconductors encompassing photodiodes, silicon photomultipliers, and infrared detectors, imaging and analyzing systems, laser equipment, and laser equipment components; the company also provides manufacturing support systems, photometry systems, life science and medical systems, semiconductor manufacturing support systems, photon counting modules, and optical measurement instruments. Founded in 1953 and headquartered in Hamamatsu, Japan, Hamamatsu Photonics operates globally through subsidiaries and affiliates across the Americas, Europe, Africa, and Asia, serving industries such as scientific research, medical diagnostics, industrial automation, telecommunications, space exploration, and semiconductors. In June 2024, the company completed the acquisition of NKT Photonics A/S, integrating its lasers and photonic crystal fibers to enhance system solutions in semiconductor, quantum, and medical applications and establishing the backbone of its laser division. More recently, in April 2025, Hamamatsu Photonics announced a strategic partnership with PredxBio to combine its MoxiePlex multiplex immunofluorescence imaging system—launched in late 2024—with PredxBio's SpaceIQ spatial analytics platform for advanced immuno-oncology research and spatial proteomics. The company continues to launch new products, including a compact 310 nm photodiode for UVB and hydrogen applications in November 2025 and a high-speed InGaAs linear image sensor in October 2025, while reporting strong sales growth in semiconductors and medical-bio segments for the fiscal year ended September 30, 2025.
