4x4 NUV Silicon Photomultiplier (SiPM) in HD Technology

Currently Viewing:

The AFBR-S4N44P163 is a 4x4-pixel silicon photo multiplier (SiPM) array for the ultra-sensitive precision counting of single photons.

The device makes efficient use of surface area by using through silicon via (TSV) technology, allowing for a high packing density without wires. Larger detector areas can be covered by tiling multiple arrays almost without edge losses.

The detector has a broad response in the visible light spectrum with particular optimization towards blue and near UV light. 

A thin glass layer highly transparent down to UV wavelength protects the array, making it well suited for the detection of scintillation or Cherenkov light from the most common scintillators, such as LSO, LYSO, GSO, BGO, NaI, CsI, BaF, LaBr.
