COUNT® S – The Inexpensive Photon Counter 
 
Passively-Quenched COUNT®

 

 

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.
