Effective immediately, a new photon counter has been added to the COUNT series: The COUNT® S features the high quantum efficiency of the other models and a significantly larger active area of 500 µm. These photon counters are passively quenched and thus the most inexpensive alternative.
A dead time of approx. 1 µs yields a maximum count rate of up to 1 Mcps. The dark count rates of the COUNT® S series range between 1000 cps and 5000 cps and tie in directly with actively quenched COUNT®s.
Incoming photons produce electrical pulses in the detector that are then readout using the TTL output. A PSU, which is available on an optional basis, completes the plug-and-play module. All models are also available with an FC/PC fiber coupling.
Our passively-quenched COUNT® S series is particularly well suited for research and school internships. For example, in the field of quantum optics and quantum information, due to the large active area, they are easier to focus on than the actively-quenched COUNT® series and the price is significantly lower.
The following versions are available and differ only in their dark count rates: COUNT® 1000S, COUNT® 2000S, COUNT® 5000S.
