1. A rearview assembly comprising:
a transflective concealment panel having a first side directed in a first direction and a second side directed in a second direction opposite the first direction wherein a reflectance at the first side is greater than a reflectance at the second side, the concealment panel comprising an asymmetric transflective coating, the asymmetric transflective coating having:
a transflective layer;
a plurality of dielectric layers disposed in the second direction relative the transflective layer; and
one or more absorptive layers interleaved with the plurality of dielectric layers; and
an imager disposed in the second direction relative the concealment panel and operable to capture light transmitted through the concealment panel and generate an image.
