The 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.
This single photon counting module detects single photons in a range of 400-1000nm. It attains 70% photon detection efficiency in the red region and comparatively higher in the blue region from the ones that are currently available in the market. It also has extremely low as 10 counts/s dark count rate than others. Well-suited for single-photon LiDAR, particle sizing, confocal microscopy, Astronomy, and quantum cryptography.
