The Electron Tube Division of Hamamatsu Photonics supports progress in the most advanced photonics technologies involving low-light-level and ultra-fast measurements. The various light-related devices we develop and produce are widely used in spectrophotometry, semiconductors, biotechnology and experimental scientific research as well as in medical applications such as blood analysis and diagnostic imaging. Based on this technology and experience in detecting low level light and ultra-fast phenomena, we have gained a high reputation for developing products that provide optimal performance even for special applications. Along with developing light sensor or photosensor products that sense light, we make ceaseless efforts to develop uniquely stable light sources that emit light. Our products offer a good balance of performance factors such as sensitivity, output level, stability, and operating life to fully meet your task and application requirements.
