Hamamatsu Photonics have introduced a completely updated range of Multi-Pixel Photon Counter (MPPC) detectors. Hamamatsu’s already highly regarded MPPC technology has found uses in various applications from medical physics and high energy physics to general optical measurement applications. A new catalogue has been released detailing the numerous performance improvements to both the bare devices and to the high performance modules.

The MPPC detectors utilize a Geiger-mode pixelated avalanche photodiode structure for ultra-low-level light detection. Each pixel contains a quenching circuit so that simultaneous photon events can be counted separately and with a high degree of accuracy. The detectors feature typical gain values from 250,000 to several million, depending on the specific device. The MPPC detectors also feature high photon detection efficiency from 320nm to 900nm. Unlike traditional photomultiplier tubes (PMT) the MPPC can be operated at low voltage (less than 80 Volts) and they are insensitive to magnetic fields.
