How a photomultiplier tube works
WebA photomultiplier tube (PMT) consists of a photocathode followed by an electron multiplier. A single photon ejects an electron from the photocathode. Electric fields in … WebPhotomultiplier tube modules. 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 components are assembled into a single compact case. We also provide modules with various additional ...

WebPhototube. A phototube or photoelectric cell is a type of gas-filled or vacuum tube that is sensitive to light. Such a tube is more correctly called a 'photoemissive cell' to distinguish it from photovoltaic or photoconductive cells. Phototubes were previously more widely used but are now replaced in many applications by solid state photodetectors.
