Abstract : The results of a round robin of measurements for the purpose of standardizing infrared directional emittance and reflectance apparatus in three laboratories are presented. Polarizers were incorporated in two of the devices, which have dispersing monochromators in their optical paths. Samples of bare polished fused silica as well as gold evaporated on polished nickel were the basis for the calibration. Their directional polarized properties were independently computed using published optical constants, and are presented here. (Modified author abstract)
