Abstract

SPADλ is a linear single-photon detector array with 320×1 single-photon avalanche diode (SPAD) pixels, featuring thermo-electric cooling for reduced noise. These SPADs offer a low dark count rate and wide detection spectrum. Equipped with microlenses, they achieve a peak photon detection efficiency of 45% at 520 nm. This system can count photons at 4 Gcps and provides time-tagging and time-gating for time-resolved detection. With 80 TDC channels, it achieves time-tagging precision averaging better than 130 ps full width half maximum (FWHM). Ideal for flow cytometry, fluorescence lifetime imaging (FLIM), and Raman spectroscopy applications.
