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 Applications Low afterpulse Scintillation measurement High fill factor Low-light-level detection High photon detection efficiency Scattered light measurement Wide operating voltage range Low dark count (no more than 1/20 the count at normal temperature through cooling) Structure Parameter Effective photosensitive area Pixel pitch Number of pixels Package Window Window refractive index Cooling Symbol - S12576-050 1×1 S12577-050 3×3 Unit mm μm - 50 400 3600 Metal (TO-8) Borosilicate glass 1.52 Two-stage TE cooler Absolute maximum ratings (Ta=25 °C) Parameter Operating temperature Storage temperature Element temperature Thermistor power dissipation TE-cooler allowable current TE-cooler allowable voltage Symbol Condition Topr No condensation Tstg No condensation Td During operation Pd_th ITE max VTE max Value -20 to +60 -20 to +85 -25 to ambient temperature 0.2 1.0 0.9 Unit °C °C °C mW A V Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality.

If the window cracks or breaks and moisture enters inside the package, condensation will form on the photosensitive surface and cause abnormal operation. ∙ See the precautions supplied with the product. 5 MPPC (multi-pixel photon counter) S12576-050, S12577-050 Related product Temperature controller for TE cooler C1103-04 The C1103-04 is a controller that maintains constant element temperature by adjusting the current that flows through a one-stage or two-stage TE-cooler.
