This is the dataset for Mid infrared high-resolution photon-counting LiDAR manuscript. This includes wavelength-dependent characterisation data of a tungsten silicide superconducting nanowire single photon detector from a wavelength of 1550 – 5438 nm alongside all data associated with the single-pixel scanning LiDAR at 3500 nm wavelength. If there are any questions regarding the acquisition of the data or detector parameters not answered in the manuscript of Supplementary Information please contact the corresponding author daniel.kuznesof@gmail.com.
