ABSTRACT:
In order to provide an optical reflectivity test plate for calibrating and proving a radiometer, which test plate exhibits a near-Lambertian surface, a ceramic coating is bonded to a surface of a rigid substrate, such as a steel plate, and the ceramic coating is thereafter sandblasted with a fine abrasive (preferably 60 grit or finer). If ordinary silica or other relatively soft abrasive is employed in the sandblasting step, it must not have have been previously used. Test procedures for comparing the resultant test plates to a standard BaSO.sub.4 test plate in both the laboratory and outdoors are given.
