Quantum efficiencies (QEs) of detectors discussed in the text. Curves were provided by the manufacturers. (a) Point-detectors, (b) wide field detectors. τ-SPAD, SPAD module sold by PicoQuant GmbH, based on a thick reach-through SPAD manufactured by Laser Components. SPCM-AQR, thick reach-through SPAD manufactured by Excelitas Technologies. RE-SPAD, red-enhanced epitaxial SPAD manufactured by Micro Photon Devices (MPD). MPD, former version of the epitaxial thin SPAD manufactured by MPD. HPD, hybrid photo detector prototype manufactured by Hamamatsu Photonics based on a GaAsP photocathode. Commercial devices including this type of modules are now available from different vendors. CMOS: 32 × 32 CMOS SPAD array prototype developed by Politecnico di Milano. EMCCD: Cascade 512B camera (Photometrics). sCMOS, scientific CMOS camera (model: neo) manufactured by Andor Technology. GaAsP, typical QE of a GaAsP photocathode (as found in the HPD shown in (a)). GaAs, typical GaAs photocathode manufactured by Photonis SA. SuperGen2, H33D Gen 2 sensitivity, based on a SuperGen2 photocathode manufactured by Photonis. S20, H33D Gen 1 sensitivity based on a multialkali S20 photocathode manufactured by UCB.
