A photomultiplier is a device that converts into an electrical signal.

Kinds of photomultiplier include:

  • Photomultiplier tube, a converting incident photons into an electric signal. Photomultiplier tubes (PMTs for short) are members of the class of , and more specifically vacuum , which are extremely sensitive detectors of light in the , , and ranges of the electromagnetic spectrum.
    • Magnetic photomultiplier, developed by the Soviets in the 1930s.
    • Electrostatic photomultiplier, a kind of photomultiplier tube demonstrated by Jan Rajchman of RCA Laboratories in Princeton, NJ in the late 1930s which became the standard for all future commercial photomultipliers. The first mass-produced photomultiplier, the Type 931, was of this design and is still commercially produced today.J. Rajchman and E.W. Pike, RCA Technical Report TR-362, "Electrostatic Focusing in Secondary Emission Multipliers," September 9, 1937.
  • Silicon photomultiplier, a solid-state device converting incident photons into an electric signal. Silicon photomultipliers, often called "SiPM" in the literature, are solid-state single--sensitive devices based on Single-photon avalanche diode (SPAD) implemented on common silicon substrate.
