Broadcom, AFBR-S4N44P164M Ultraviolet, Visible Light 16-Element Photomultiplier, 420nm

The Broadcom 4x4 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.
