Low afterpulse
When an MPPC detects photons, the output may contain spurious signals appearing with a time delay from the light input to the MPPC.
These signals are called afterpulses. Compared to our previously marketed products, the S12571 series have drastically reduced afterpulses
due to use of improved materials and wafer process technologies. Reducing afterpulses brings various benefits such as a better S/N, a
wider operating voltage range, and improved time resolution and photon detection efficiency in high voltage regions.
