An electronic sensing device used to detect weak electromagnetic radiation, typically light, and amplify its energy via the photoelectric effect.


(General Physics) a device sensitive to electromagnetic radiation, consisting of a photocathode, from which electrons are released by incident photons, and an electron multiplier, which amplifies and produces a detectable pulse of current


(ˌfoʊ təˈmʌl təˌplaɪ ər)

a light detector that amplifies a photon's signal by using a photocathode and a series of electrodes to create a cascade of electrons.
