Our SIPMs facilitate the realization of two-dimensional (2D) position-sensitive (PS) SiPMs, which have the attractive advantages of fewer output electrodes, simple readout electronics, and high position resolution.

Silicon photomultiplier (SiPM) is composed of avalanche photodiode arrays operating above the avalanche breakdown voltage and having an avalanche quenching mechanism in parallel. It has excellent photon number resolution and single-photon detection sensitivity. The silicon-based low-light detector has a very important and wide range of applications in particle physics and nuclear physics research, nuclear medicine diagnosis and treatment, lidar, fluorescence detection and other fields.
