AFBR-S4N22P014M

AFBR-S4N22P014M is a single-channel silicon photomultiplier (SiPM) array that is used for ultrasensitive precision measurements of single photons. This SiPM is based on NUV-MT technology, which combines improved photo-detection efficiency (PDE) with decreased dark count rate and reduced crosstalk compared to the NUV-HD technology. The SPAD pitch is 40μm. Larger areas can be covered by tiling multiple AFBR-S4N22P014M SiPMs. The encapsulation for good mechanical stability and robustness is realized by an epoxy clear mold compound, which is highly transparent down to UV wavelengths, resulting in a broad response in the visible light spectrum with high sensitivity toward the blue and near-UV region of the light spectrum. It is used in applications such as X-ray and gamma-ray detection, nuclear medicine, positron emission tomography, safety and security, physics experiments, Cherenkov detection.
