Abstract Reflectance standards are prepared in accordance with the present invention by incorporating at least 40 percent by weight of barium sulphate into acrylate polymer such as methyl acrylate or methyl methacrylate. Thickness of the resulting polymer should be in excess of 0.25 centimeters. By incorporating varying percentages of carbon black in the mixture during mixing - various reflectance values can be obtained. The resulting reflectance standards can be utilized in the form of chips, plaques, sheets, or can be molded into various configurations, including that of an integrating sphere.
