Hamamatsu Photonics K.K. (浜松ホトニクス株式会社 Hamamatsu Hotonikusu Kabushiki-gaisha?) is a Japanese manufacturer of optical sensors (including photomultiplier tubes), electric light sources, and other optical devices and their applied instruments for scientific, technical and medical use.[2]

The company was founded in 1953 by Heihachiro Horiuchi, a former student of Kenjiro Takayanagi, who is known as "the father of Japanese television".[3]

Hermann Simon, a leading German business author and thinker, mentioned Hamamatsu in his book titled Hidden Champions of the Twenty-First Century: The Success Strategies of Unknown World Market Leaders as an example of a "Hidden Champion".[2]

Hamamatsu CCD image sensors are used at the Subaru Telescope of the National Astronomical Observatory of Japan.[4]
