Source: Wikipedia Understanding Photon Counters Photon counters are photodetectors that are so sensitive that they can detect single photons. This capability allows for the registration of individual photon absorption events rather than measuring optical intensity or power. Photon counters are crucial for experiments in quantum optics where coincidences between multiple detectors need to be recorded.
