S12571-010C Datasheet, PDF (1/6 Pages) Hamamatsu Corporation – multi-pixel photon counter

MPPC^® (multi-pixel photon counter)
S12571-010, -015C/P
Low afterpulses, wide dynamic range,
for
high-speed measurement
Photosensitive area: 1 × 1 mm
These MPPCs utilize very small pixels arrayed at high densities to achieve a high-speed recovery time and wide dynamic
range. Hamamatsu currently produces MPPC with a pixel density up to 10000 pixels/mm² (pixel pitch: 10 μm). Utilizing
advanced technology to enhance photon detection efficiency minimizes the drop in photon detection efficiency that usually
occurs due to shrinking the pixel pitch.
Features
Low afterpulse
High fill factor
High photon detection efficiency
Wide operating voltage range
Short recovery time
High count rate
Applications
Scintillation measurement
Low-light-level detection
Scattered light measurement

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.
