We offer Silicon Photomultipliers (SiPMs) manufactured in Germany by KETEK GmbH using leading edge CMOS wafer fabrication and wafer-level glass-window surface mount packaging.
SiPMs are rapidly replacing conventional vacuum photomultiplier tubes (PMTs), silicon avalanche photodiodes (APDs) and silicon photodiodes in a wide range of high speed and low light sensing applications due to a combination of exciting features:-
Low operating voltage - less than 30V
Tightly controlled breakdown voltage - 300mV
Low temperature dependence of breakdown voltage - 22mV
High Gain & SNR
Immunity to magnetic fields
MRI compatible packaging
Small size whilst mechanically and optically robust with no damage from high-light levels
Multi-channel arrays can be made with fine pitch resolutions not possible in vacuum PMTs
In summary, KETEK SiPMs combine the benefits of vacuum PMTs (high photon detection efficiency, gain and signal-to-noise) with those of APDs (robustness, miniaturised design, low operation voltage, cost-effective and magnetic insensitivity) to produce an outstanding low level light sensor with exceptional performance at low cost.
