SPCM-AQRH-TR

The Excelitas SPCM-AQRH-WX-TR is a Single Photon Counting Module of the latest product generation, specifically selected and performance-optimized for timing resolution. This family of –TR modules is designed to support applications in time-correlated single-photon counting (TCSPC), fluorescence lifetime measurements and fluorescence lifetime imaging microscopy (FLIM).

The SPCM-AQRH-WX-TR uses a specially selected SLiK silicon avalanche photodiode with timing resolution better than 250 ps while maintaining peak photon detection efficiency (PDE) of more than 75% at 650 nm over a 180 µm diameter active area. While some performance parameters, in particular afterpulse probability, are traded off against the optimized timing performance, other performance parameters of the standard SPCM-AQRH, such as outstanding uniformity, overload protection, temperature stability and linearity, are still maintained by this timing-optimized module.
