07 Oct 2021 LASER COMPONENTS designs and manufactures a range of single photon counting modules (SPCM) utilising its own exclusive avalanche photodiodes (APDs) to offer market leading quantum efficiency and exceptionally low dark count rates. Several variants of the COUNT modules are available which are optimised for different application requirements, from NIR optimised modules typically utilised for quantum cryptography to high timing precision variants optimised for applications such as time correlated single photon counting and fluorescence lifetime imaging. Typical spectral response curves for our NIR and blue wavelength variants are shown here.
Our COUNT modules feature a simple robust design combining a low noise APD, two stage thermo-electric cooler and thermistor with specially developed quenching and signal processing electronics. An optional fibre connector can also be offered, providing a convenient method for sampling from a multimode optical fibre. We have recently invested in improvements to our production and test facilities which enable shorter lead times. Requests for custom versions are also welcomed.
