Single Photon Detection has become a vital tool in many applications – single molecule fluorescence, particle characterization through scattering, Quantum Cryptography, astronomy, LiDAR and more. The concept appears to be simple in principle, but how easy is it to detect a single electron? This whitepaper covers the evolution of silicon single photon counting from the original principle through to today’s turn-key modules that now provide simple, plug-and-run photon detection for OEMs and laboratories alike.
