KETEK Silicon Photomultipliers

KETEK Silicon Photomultipliers (SiPMs) are state-of-the-art low level light photodetectors with highest photodetection efficiency of > 50% and excellent time resolution of < 215 ps FWHM for a single photon. In addition they feature an outstanding temperature and operational stability. KETEK SiPMs are not only usable for single photons, but can also detect bright light flashes without degradation or damaging of the detector.

They are sensitive to visible light from 350 to 900 nm with the maximum photodetection efficiency in the blue at 430 nm. These properties make them an excellent choice for direct photon detection as well as scintillator readout.

With their high sensitivity, speed, compactness and robustness they are an excellent replacement for classical photomultiplier tubes and avalanche photodiodes. KETEK SiPMs can unlock application performance beyond the traditional approaches.

KETEK SiPMs are available in sizes of 1.2 x 1.2 mm², 3.0 x 3.0 mm² and 6.0 x 6.0 mm²  in a package suitable for industrial applications.
