Single-Photon Counting

Photonics Spectra
Oct 2011
Laser Components GmbHRequest Info
The COUNTblue series single-photon counting modules manufactured by Laser Components GmbH achieve a quantum efficiency of 60% in the blue spectral range and 70% in the yellow and green wavelengths. The heart of the series is a blue-enhanced silicon Geiger-mode low-noise avalanche photodiode that, together with optimized electronics, produces dark count rates of 10 to 250 counts per second. Suitable for use in fluorescence measurement, the modules are available with an FC connection for optical fibers with a core diameter up to 105 µm, or as a free-beam version. They are plug-and-play-compatible with standard photon counters available on the market.
