Product Overview
The Broadcom AFBR-S4N22P014M is a single-channel silicon photomultiplier (SiPM) array designed for ultra-sensitive precision measurements of single photons. Utilizing NUV-MT technology, it offers enhanced photo-detection efficiency (PDE) and reduced dark count rate and crosstalk compared to NUV-HD technology. Its epoxy encapsulation ensures mechanical stability and robustness while maintaining high transparency down to UV wavelengths, providing broad spectral response with high sensitivity in the blue and near-UV regions. This SiPM 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.
