The Broadcom AFBR-S4N44P044M is a 2x2 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 previous technologies. Its epoxy encapsulation ensures mechanical stability and transparency down to UV wavelengths, providing broad spectral response with high sensitivity in the blue and near-UV regions. This array is ideal for detecting low-level pulsed light sources, particularly Cherenkov or scintillation light from common organic and inorganic scintillator materials. It is lead-free and RoHS compliant.
