Offers a high count rate solution. The detection efficiency of SNSPDs may decrease at higher incoming light levels. The count rate at which the detection efficiency decreases by 3 dB from the peak detection efficiency is defined as the maximum count rate. It is measured with laser pulsed at a required repetition rate.
