Hamamatsu Photonics
The company Hamamatsu Photonics K. K. (Japanese浜松 ホトニクス 株式会社, Hamamatsu Hotonikusu Kabushiki - gaisha ) is a Japanese manufacturer of optoelectronic sensors, light sources and opto- electronic components and instruments.
History
The 1983 trading under the name of Hamamatsu Photonics Company was founded in 1953 as a Hamamatsu TV Co., Ltd.. founded by Horiuchi Heihachiro in Hamamatsu (Japan ), a former student of Kenjiro Takayanagi, the father of Japanese television.
The company began in the 1950s with the production of photocells and photomultipliers. In the 1960s, advanced vidicon and the late 1970s, photodiodes and optical position sensors, the product range. 1973 established a branch in Germany with the Hamamatsu Television Europe GmbH (now Hamamatsu Photonics Germany GmbH). Today Hamamatsu Photonics is one of the leading manufacturers of optoelectronic sensors with a global market share of 60 % (as of 2007).
Among other things, Hamamatsu Photonics has developed in the early 1980s the largest ever built R1449 photomultiplier with about 50 cm in diameter. By May 1982, the company delivered 1,050 units of this Kamioka Nucleon Decay for the experiment. For the neutrino detector of the follow-up project Super - Kamiokande 11,200 units of the successor model R3600 -05 were delivered in the 1990s.
Hamamatsu Photonics is still one of the supplier of the detectors ( ATLAS, CMS, LHCb and ALICE ) of the Large Hadron Collider at the European Organization for Nuclear Research CERN in Geneva. For participation in the development, improvement and production of avalanche photodiodes ( 140,000 units) for the electromagnetic calorimeter of the CMS and silicon strip detectors ( 22,000 units) for the CMS Tracker for tracking the particles produced, the company was founded in 2003 and 2005 with the CMS Crystal Award of CERN excellent.
Products
- Sensors: To the photo detectors of the range include the use of the external photoelectric effect, inter alia, photomultiplier, microchannel plate photomultiplier and image intensifier. Using the photodetectors, the inner photoelectric effect include CCD and CMOS sensors, PIN photodiodes and avalanche photodiodes, and optical position sensors ( Position Sensitive Device). A plurality of semiconductor detectors for X-rays or infrared rays are produced.
- Light sources: The product range here includes light sources such as gas discharge tubes, hollow cathode lamps, semiconductor lasers and light emitting diodes.
- Optoelectronic Instruments: These include spectrometer and fluorescence spectrometer, and CCD, EM - CCD, CMOS and streak cameras.
Competitor
In the field of semiconductor sensors and cameras are among the main competitors e2v Technologies (UK), PerkinElmer (USA) and Micron Technology (USA). Photomultiplier are produced by only a few other companies around the world, such as from the Photonis Group ( France, Netherlands, USA ), ET Enterprises ( UK) and ADIT (USA).
