Information

all about SPCMs

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. 

In this product section you will also find avalanche photodiodes to build your own SPCM.
