We present new high-contrast imaging observations of the circumbinary brown dwarf HII 1348B $\\mathord{-}$ one of the few known substellar companions in the Pleiades cluster. We observed the system in the infrared (IR) $L^\\prime$ band with the Large Binocular Telescope Interferometer (LBTI) in dual-aperture direct imaging mode (i.e., with the two telescope apertures used separately) on 2019 September 18.
