Product Overview
The Broadcom AFBR-S4N44P164M is a 4x4 silicon photomultiplier (SiPM) array designed for ultra-sensitive precision measurements of single photons. Leveraging NUV-MT technology, it offers enhanced photo-detection efficiency (PDE) and reduced dark count rate and crosstalk compared to NUV-HD technology. Its 4 mm pitch allows for tiling to cover larger areas with minimal edge loss. Encased in a highly transparent epoxy mold compound, it exhibits broad spectral response with high sensitivity in the blue and near-UV regions. This array is ideal for detecting low-level pulsed light sources, including Cherenkov or scintillation light from common organic and inorganic scintillator materials. It is lead-free and RoHS compliant.
