Photon counter COUNT® T

lasertime-correlated

Single photon counting modules. So-called single photon counting modules are used to count single photons. These photon counters, sold under the brand name COUNT®, offer phenomenally low dark count rates and a high detection efficiency. Single photon counter for time-correlated applications Time-Correlated Photon Counting In time-correlated single photon counting (TCSPC), single photons are counted and the time of detection is determined based on a reference signal. Here, a laser pulse generally serves as a reference. This method is a statistical counting method. The COUNT® T is equipped with an avalanche photodiode produced in house and features a high detection efficiency, and a temporal resolution of up to 350 ps.
