AFBR-S4N44P164M

AFBR-S4N44P164M is a Broadcom® 4×4 NUV-MT silicon photomultiplier array used for ultra-sensitive precision measurements of single photons. This SiPM is based on NUV-MT technology, which combines improved photo-detection efficiency (PDE) with a decreased dark count rate and reduced crosstalk compared to NUV-HD technology. The pitch of SiPMs is 4mm in both directions. Larger areas can be covered with a pitch of 16mm by tiling multiple AFBR-S4N44P164M arrays almost without any edge losses. 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. The Applications include X-ray and gamma-ray detection, nuclear medicine, positron emission tomography, safety and security, physics experiments, and Cherenkov detection.
