| | | A Single Compact Package for Easy Use ■FUNCTIONS Photomultiplier Tube (PMT) module functions are shown in the chart below. PMT modules are 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. | | |
