PMT (photomultiplier tubes)

In the photosensor field, photomultiplier tubes (or PMT) are known to have particularly high sensitivity. PMT also have dozens of other advantages such as high-speed response time.

PMT modules

The PMT module is basically comprised of a photomultiplier tube to convert light into electrical signals, a high-voltage power supply circuit, and a voltage divider circuit to distribute the optimum voltage to each dynode, all assembled into a single compact case. In addition to these basic PMT modules, Hamamatsu also provides modules having various additional functions such as signal processing, cooling and interface to PC.



HAMAMATSU mini-spectrometers are polychromators integrated with optical elements, an image sensor and a circuit. Light to be measured is guided into the entrance port of through an optical fiber and the spectrum measured with the built-in image sensor is output from the USB port to a PC for data acquisition.
