High Performance Multi-Pixel Photon Counter Detectors

Hamamatsu Photonics´ Multi-Pixel Photon Counter (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. They also feature high photon detection efficiency from 320 nm to 900 nm. Unlike traditional photomultiplier tubes the MPPC can be operated at low voltage and they are insensitive to magnetic fields.

It is ideally suited for positron emission tomography, high-energy physics, DNA sequencing, fluorescence measurement, nuclear medicine, drug discovery, environmental analysis among many more.
