Potential of the next generation VHE instruments to probe the EBL (I): The low- and mid-VHE

► The next generation Cherenkov telescope system will enable to derive new strong limit on the density of the EBL. ► Broad energy coverage enables to simultaneously measure the un-absorbed (< 100 GeV) and the EBL attenuated part (> 100 GeV) of the spectra of extragalactic sources. ► High sensitivity at > 100 GeV might enable to measure the absolute level of the EBL density.
