Description

The ID Quantique ID230 InGaAs SPAD delivers an instrument response width of 80 ps FWHM with the bh SPC-150N TCSPC module. This is the fastest TCSPC response reported for InGaAs SPADs so far. Compared to its predecessor the new InGaAs SPAD also has a much lower dark count rate. The detector we tested had less than 300 dark counts when operated with a dead time of 40 μs. The IRF width with an SPC-150N TCSPC module was about 80 ps, fwhm, see figure below. For details, please see 80 ps FHWM Instrument Response with ID230 InGaAs SPAD and SPC-150 TCSPC Module.
