Photomultiplier
A photomultiplier is a device that converts
electrical signal
.
Kinds of photomultiplier include:
- near-infrared 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.[1]
- solid-state device converting incident photons into an electric signal. Silicon photomultipliers, often called "SiPM" in the literature, are solid-state single-photon-sensitive devices based on Single-photon avalanche diode (SPAD) implemented on common silicon substrate.[2][3]
