In 2010, LASER COMPONENTS introduced yet another innovative product into the market: complete single photon counting modules. Laser Components successfully met the demands of its customers for a high quantum efficiency and very low dark count rates with these modules.

At the heart of the COUNT modules is a Geiger-mode silicon avalanche photodiode, which was specifically developed by the LASER COMPONENTS Detector Group. This APD is one of the lowest-noise photodiodes on the market and features an excellent quantum efficiency in the blue and red spectral regions.

Both the production facility and testing laboratories for inspection, measurement, and qualification of the COUNT modules are located in Olching (Germany).
