AFBR-S4N44P044M - 2x2 NUV-MT Silicon Photomultiplier Array

Product Detail

The Broadcom® 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 4 mm in both directions. Larger areas can be covered with a pitch of 8.3 mm 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 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 array is best suited for the detection of low-level pulsed light sources, especially for detection of Cherenkov or scintillation light from the most common organic (plastic) and inorganic scintillator materials (for example, LSO, LYSO, BGO, NaI, CsI, BaF, LaBr3). This product is lead-free and compliant with RoHS.
