In the lbne-DocDB document # 4134, Bruce Baller showed some calculations of photon transmission through the TPC wire planes. As a reality check, we have measured light transmission through the existing 6-plane prototype in Lab 6, for normal incidence and 45 degree incidence. The results agree well with the predictions of the simple formula in Bruces paper.
