Webrepresents the light intensity. Therefore, counting the detector pulses within defined time intervals - i.e. photon counting - is the most efficient way to record the light intensity with a high gain detector [1]. Steady State Photon Counting Simple intensity measurement of slow signals can easily be accomplished by a high-gain WebThis button displays the currently selected search type.
