Photodiode Detector

The S10362-11 series MPPC (multi-pixel photon counter) detects ultra-low-level light in applications including positron emission tomography, high-energy physics, DNA sequencing, fluorescence measurement, and environmental analysis. The series has an active area of 1 mm × 1 mm, and is available in three pixel counts (100, 400, or 1600 pixels). Each pixel contains a quenching circuit so that simultaneous photon events can be counted separately and with a high degree of accuracy. Other key characteristics of the S10362-11 include high gain (approximately 1 × 10₆), high photon detection efficiency, and peak sensitivity at 400 nm. The series can be operated at low voltage (less than 100 V) and is insensitive to magnetic field effects.
