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 with the best low noise characteristics.

Record-breaking Dark Count Rate, 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!

The COUNT® Q features an integrated InGaAs APD and covers the spectral range from 900 nm to 1600 nm.
