                         allowed obtaining more accurate data due to atmospheric absence. 
                         The instruments used in these measurements are electrical 
                         substitution radiometers, which use cavity-type sensors. This work 
                         shows the ideal geometric parameters for these sensors considering 
                         a paint with specular characteristics. The study was carried out 
                         using non-sequential ray tracing for a cone and for a 
                         cone-cylinder cavity. The best results were obtained for a cone 
                         length to diameter ratio of 1.5 whereas for a cylinder, a 
                         reduction of up to 80% could be obtained.",
