Becker & Hickl offers a wide range of detectors including photomultiplier tubes, hybrid photodetectors, single-photon avalanche diodes for the IR range, and multi-channel and multi-spectral detectors. Time resolution for the fastest detectors is in the sub-20-ps range. The detectors are suitable for fluorescence-decay recording by classic TCSPC, anti-bunching, FCS, FLIM, PLIM. BH guarantees that their TCSPC modules work with any photon counting detector, including superconducting NbN detectors and reach the shortest possible IRF width.
