AFBR-S4N44P044M

AFBR-S4N44P044M is a 2 × 2 silicon photo multiplier (SiPM) array used for ultra-sensitive precision measurements of single photons. This SiPM is based on the 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 pitch of the SiPMs is 4mm in both directions. Larger areas can be covered with a pitch of 8.3mm by tiling multiple AFBR-S4N44P044M arrays almost without any edge losses. The encapsulation for good mechanical stability and robustness is realized by an epoxy clear mould compound, which is highly transparent down to UV wavelengths. It is used in applications such as X-ray and gamma ray detection, nuclear medicine, positron emission tomography, life sciences, flow cytometry, cell sorting, safety and security, physics experiments, cherenkov detection.
