Hamamatsu Photonics products and technology include optical sensors, light sources, and systems that use these components. They are applied to various new technologies and devices to support people’s lives and help realize a more comfortable and prosperous society. Our products are widely used for state-of-the-art medical equipment, test and inspection systems, microscopes that reveal the functions of cells, and giant telescopes that explore the mysteries of the universe. Portable and high-sensitivity radiation detectors are used by police, custom inspectors, and others to detect radioactive substances (alpha particles, beta particles, gamma rays, and x-rays), as well as neutrons. We offer a wide selection of photodetectors designed for use with scintillation-based detectors.
