Single photon counting modules. So-called single photon counting modules are used to count single photons. These photon counters, sold under the brand name COUNT®, offer phenomenally low dark count rates and a high detection efficiency.
Single photon counting modules with record-breaking dark count rate and highest quantum efficiency
Single photon counting modules with even higher efficiencies at shorter wavelengths.
Single photon counting modules with a detection efficiency >50% at 810 nm!
