Supplementary Figure 1: The SPAD array detection system developed for image scanning microscopy.

Photograph of the SPAD array detection system. The photograph shows the two stacked printed circuit boards (PCBs). Inset shows the 5 × 5 SPAD array. (b) Photon detection efficiency (PDE) of the central element of the 5 × 5 SPAD array, at different excess bias voltages. (c) Temporal response (or impulse-response function (IRF)) of the central element (Vex = 6 V excess-bias) of the SPAD array to a pulsed laser source at 850 nm (20 ps FWHM) when all the other pixels are turned ON. The long tail on the right side of the IRF is due to the optical cross-talk with the other SPAD elements.
