We report a novel wide-field imaging method capable of time-correlated single photon counting. It is based on a photon counting image intensifier coupled to an ultra-fast CMOS camera running at 40 kHz frame rate. Using a pulsed excitation source and decaying luminescent sample, the arrival times of hundreds of photons can be determined simultaneously in many pixels with microsecond resolution and reduced photon pile-up. The detection system is mounted on an inverted microscope and applied to time-resolved imaging of Europium-containing polyoxometalate nanoparticles.
