| dc.description | A simple, direct, and absolute method of reflectometry is described, avoiding the use of the inverse square law, and overcoming several of the drawbacks of the selenium photovoltaic cell which is used for the measurements These advantages are secured through the use of calibrated apertures and certain integrating properties of the cell. The result obtained for the luminance factor for white light of an MgO smoked layer 1 mm thick was 1.01 for normal incidence and 45° view |
