The Hamamatsu Photonics Central Research Laboratory is home to a host of facilities where specialized research is carried out in a variety of fields, among them the Research Center, the Material Center, the PET Center, the Positron Medical Center, and the Biotechnology Center. "Photonics" is a common theme running through both the fundamental research and applied research being conducted here.

Research using light, rather than asking "What can be done?", In considering an endless spectrum of methods and determining which will serve the most useful purpose to mankind, our starting point is the point at which research using light meets up with society's needs. This is the primary reason that we keep an open mind concerning the contents of our research, and we welcome access from all kinds of scholarly and industrial fields.
