(multi-pixel photon counter) S12571-025, -050, -100C/P Low afterpulse, for general measurement Photosensitive area: 1 × 1 mm 1www.hamamatsu.com The S12571 series are general-purpose MPPC with drastically reduced afterpulses compared to our previously marketed products. By widening the operating voltage range and improving the time resolution and photon detection ef fi ciency, the S12571 series offer the characteristics needed for a variety of applications. These MPPCs have a photosensitive area of 1 × 1 mm and are available in a ceramic package or surface mount type. Superior photon counting capability (superior photon detection effi ciency against incident photons) Fluorescence measurement MPPC module C11205-150 Flow cytometry DNA sequencer Environmental analysis PET High energy physics experimentOperates at room temperature Significantly reduced afterpulses (compared to previous products) Low voltage (100 V or less) operation High gain: 105 to 106 Immune to the effects of magnetic fields Superior time resolution Compact Operates with simple readout circuits MPPC module also available (sold separately) Related product (sold separately) When an MPPC detects photons, the output may contain spurious signals appearing with a time delay from the light input to the M PPC. 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 bene fi ts such as a better S/N, a wider operating voltage range, and improved time resolution and photon detection effi ciency in high voltage regions.

The 25 μm pixel pitch type is suitable for applications requiring a wide dy- namic range, because it has a large number of pixels and provides narrow-width output pulses. The 100 μm pixel pitch type is suitable for applications where high gain is essential. Although increasing the operating voltage improves the photon detection effi ciency and time resolution, it also increases the dark count and crosstalk at the same time, so an optimum operating voltage must be selected to match the application.
