Photon counting using hamamatsu c30902e
WebFor photon counting, detectors with intrinsic gain are necessary. A commonly used detector is a photomultiplier tube, which uses dynodes to provide intrinsic gain to the detector. Photodiodes do not have intrinsic gain which means 1 incident photon will, at most, allow the flow of 1 electron, which is too small of a signal to overcome the noise. WebMay 18, 2024 · Using the SPDC photon-pair source results in an increase in the two-photon event to one-photon event ratio by a factor of 1.66 when compared to the LED photon source.
