Hamamatsu Photonics K.K. 

Hamamatsu Photonics K.K. (HPHTF) is a global leader specializing in the development and manufacturing of advanced optoelectronic devices and systems. The company's core offerings include photomultiplier tubes, various imaging technologies, diverse light sources, cutting-edge opto-semiconductors, and comprehensive imaging and analytical systems, all distributed across Japan and international markets. Its extensive operations are organized into three distinct segments: Electron Tube, Opto-Semiconductor, and Imaging and Measurement Instruments. The product portfolio is broad, featuring a wide spectrum of optical sensors such as photodiodes, avalanche photodiodes (APDs), photo ICs, multi-pixel photon counters (MPPCs/SPADs), photomultiplier tubes, phototubes, and infrared detectors. It also supplies specialized sensors for applications including spectroscopy, UV light, flame detection, general imaging, X-ray, radiation, electron/ion detection, and distance/position measurement. Additionally, Hamamatsu Photonics provides essential optical components like optical blocks, fiber optic plates, various types of lenses (FAC, collimating capillary), capillary plates, flow cells, optical phase modulators, image splitting optics, MEMS mirrors, and advanced substrates such as SERS and DIUTHAME for ionization assistance, alongside terahertz wave plates. The company further produces a range of cameras, encompassing standard, board-level, and X-ray cameras, complemented by its own imaging software. Its comprehensive selection of light and radiation sources includes LEDs, various types of lamps (including UV-LED and excimer), as well as microfocus, soft, extreme ultraviolet, and advanced laser-driven light sources. Furthermore, it develops semiconductor, solid-state, and other specialized laser products. Beyond its core scientific and industrial endeavors, Hamamatsu Photonics also diversifies its interests through hotel operations. The company, originally established in 1953 as Hamamatsu TV Co., Ltd., is headquartered in Hamamatsu, Japan.
