NUV-HD Single Silicon Photo Multiplier

Currently Viewing:

The AFBR-S4N44C013 is a single silicon photo multiplier (SiPM) used for ultra-sensitive precision measurement of single photons.

The active area is 3.72 x 3.72 mm2. High packing density of the single chips is achieved using trough-silicon-via (TSV) technology. Larger areas can be covered by tiling multiple AFBR-S4N44C013 arrays almost without any edge losses. The passivation layer is made by a glass 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 -- LSO, LYSO, BGO, NaI, CsI, BaF and LaBr, as examples.
