A photomultiplier tube is a non-thermionic vacuum tube, usually made of glass, that converts very small light signals into a measurable electric current. Photomultiplier Tube Base Comparison Chart High Model Voltage (Vmax) Bleeder Current (mA) PM Output Signals Control Compatible with PMT Type Dimensions Anode Dynode 265A PMT Base –3000 ≤2 Neg. Its inner workings are straightforward: The photoelectric effect, also called photoemission, arises when a body, struck by light, emits electrons.
