Photon-counting detectors

Photon-counting detectors are sensitive devices that measure individual particles of light, called photons. They operate by detecting when a photon hits a sensor, then converting that event into an electronic signal. This technology allows for extremely precise measurement of low light levels and can distinguish very faint signals from background noise. Photon-counting detectors are widely used in scientific research, medical imaging, and astronomy, where detecting minimal amounts of light with high accuracy is essential. Their ability to count photons individually provides unparalleled sensitivity and resolution, enabling detailed observations and measurements in various fields.
