Multi-Pixel Photon Counters (MPPCs/SiPMs)

Our Multi-Pixel Photon Counter (MPPC), also known as silicon photomultiplier (SiPM), is a solid state photomultiplier comprised of a high density matrix of Geiger-mode-operated avalanche photodiodes also known as SPAD (single-photon avalanche photodiode). These SPADs have high internal gain which enable single photon detection. The Hamamatsu SiPM features low dark count, high photon detection efficiency, excellent timing resolution, low bias voltage operation, ruggedness, resistance to excess light, and immunity to magnetic fields. They are well-suited to single photon counting and other ultra-low light applications.

Single MPPCs (SiPMs) and multi-channel MPPCs

Modules (SiPM modules) that contain an MPPC capable of detecting extremely low-level light.

Single-Pixel Photon Counter (SPPC) is a type of SPAD device. It is a single-photon avalanche diode used in single-photon detection applications, where it is often involved in photon counting. Hamamatsu offers SPAD array and module products, and we can integrate these detectors with ASIC and customize our products to fit into your unique system. SPAD sensors can be used in LiDAR, optical tomography, quantum computing, and other low-light-level applications.

Power supplies and driver circuits for MPPCs. Power supplies have a built-in temperature compensation function to stabilize MPPC operation in environments with fluctuating temperatures.
