S12576-050_15 Datasheet, PDF (1/7 Pages) Hamamatsu Corporation – Low afterpulse, for very low light-level measurement Photosensitive area: 1 x 1 mm, 3 x 3 mm
MPPC® (multi-pixel photon counter)
S12576-050 S12577-050
Low afterpulse, for very low light-level measurement
Photosensitive area: 1 × 1 mm, 3 × 3 mm
These MPPCs have thermoelectric coolers to prevent the S/N from degrading due to dark count. For every approximately
8 °C reduction in element temperature, the dark count is halved.
Features
Low afterpulse
High fill factor
High photon detection efficiency
Wide operating voltage range
Low dark count (no more than 1/20 the count at
normal temperature through cooling)
Applications
Scintillation measurement
Low-light-level detection
Scattered light measurement
