In 2010 Laser Components GmbH 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 our sister company Laser Components Detector Group, Inc. 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.

Manufacturing Options
At the semi-automatic measuring station, quantum efficiency, dark count rates, and after-pulsing can be measured - with or without fiber coupling. We simulate different scenarios, testing efficiency in your application field.

Both the production facility and testing laboratories for inspection, measurement, and qualification of the COUNT^® modules are located at our headquarters in Olching.
