Also called single photon counting. The recording of sequential single photon pulses counted by way of recording the electron emission events from a photosensitive layer (photocathode) and multiplied by means of a ‘dynode’ arrangement (photomultiplier).

DCS300PA is a low noise, high gain, trans-impedance amplifier and data acquire system. The DCS300PA can be used as a normal DAQ system for low signals. It’s also used with Zolix photodevice.
