Silicon Photomultipliers (SiPMs) are silicon-based solid state low level light sensors. They are basically an array of silicon avalanche photo diodes (APDs), each operated in Geiger-mode. This results in the SiPM’s advantages of high gain, low temperature dependency, easy operation and enhanced next generation sensor performance.
KETEK Silicon Photomultipliers (SiPMs) are novel solid-state silicon detectors with single photon counting capability. SiPMs excel in many applications and feature high gain with very low temperature drift, extremely good timing performance at a low operating voltage. They are also insensitive to magnetic fields and stand out with their mechanical robustness. KETEK provides cost-effective solutions from high volume applications to customized detector solutions.
