We studied the transmission of positronium through thin graphene films supported with lacy carbon using an energy-tunable positronium beam recently developed based on photodetachment of positronium negative ions. By analysing the results of the measurements conducted with different number of graphene layers, the transmittance per single-layer graphene without lacy carbon was estimated to be 70% and 74% at 2.3 keV and 3.3 keV, respectively.
