Excelitas now offers high photon detection efficiency Silicon Photomultipliers (SiPMs) within their low light level detection portfolio.
SiPMs are arrays of parallel, interconnected avalanche photodiodes (APDs) which benefit from low-noise, low-cross-talk and ultra-fast timing resolution. Operated in a voltage range above the breakdown voltage, they provide high Photon Detection Efficiency (PDE) from near UV to NIR wavelengths. SiPMs allow multiple photons to be detected and counted within the same timeframe, and offer high linearity and high dynamic range.
One of the biggest advantages of SiPMs - as compared to traditional photomultiplier tubes (PMTs) – is their high immunity to electromagnetic fields.
Excelitas’ SiPMs are suited to high-volume applications in:
Single Photon Emission Computed Tomography (SPECT)
High Energy Physics
