Hamamatsu Photonics K.K. is a Japanese manufacturer of optical sensors, electric light sources, and other optical devices and their applied instruments for scientific, technical and medical use.

History[edit | edit source]

Founded by Heihachiro Horiuchi, who was taught by Kenjiro Takayanagi. Started out manufacturing vacuum tubes and CRTs for television. Maintains high technology in special optical equipment, including photomultiplier tubes. Later, through the strengthening of semiconductor-related equipment, it also developed semiconductor lasers and photodiodes.

Hamamatsu TV[edit | edit source]

Founded on September 29,1953 as Hamamatsu TV Co. Ltd.

Hamamatsu Photonics[edit | edit source]

The company name was changed to Hamamatsu Photonics K.K. in 1983.

Listed on the Second Section of the Tokyo Stock Exchangein 1996, and on the First Section in 1998.

In 2002, Masatoshi Koshiba was awarded the Nobel Prize in Physics for his work on neutrino observation using the Kamiokande detector, which was equipped with a large number of Hamamatsu Photonics 20-inch photomultiplier tubes. For this reason, the photomultiplier tubes themselves made by Hamamatsu Photonics were also recognized as an IEEE Milestone on October 16, 2014.

The same type of photomultiplier tube was also used in research at the Super-Kamiokande, which contributed to the Nobel Prize in Physics awarded to Takaaki Kajita in 2015.[1]

Image intensifiers[edit | edit source]

Hamamatsu mostly manufactures intensifier tubes for scientific purposes, but also image intensifiers for use in night vision devices. Gen2+ and Gen3[2]. Hamamatsu currently develops two image intensifiers with power supplies included, the V6833P and the V7090P with a -G option for the 6833 for Autogating.[3]
