Applications: Quantum measurement, single photon detection

General Description 

The SPC-Vis a single photon detector that comes with a time to digital converter, TDC1 that gives timestamps up to 2ns in resolution. The APD has a photo detection efficiency of about 60%. The TDC1 can also be used in counter mode that integrates all the pulses from the APD in a settable integration time from 1 to 65535 ms.
