The Electron Tube Division of Hamamatsu Photonics produces a variety of detectors for x-ray, ultraviolet, visible and near infrared, all featuring high sensitivity. Photomultiplier tubes provide signal gain as high as 5 x 106 that is almost free from excess noise. Many of the detectors can operate at high frequencies and are capable of capturing events of short duration or at extremely low light levels. Image intensifiers, ion, electron detectors and microchannel plates (MCP) are also available. Many types of detectors can be customized to a specific application. Our detectors are used in applications such as medical imaging, analytical chemistry, DNA sequencing, scientific research, fire detection and security.
