La energía solarpuede satisfacer las necesidades de la población mundial. La energía solar concentrada utiliza superficies espejadas que reflejan y concentran los rayos en un receptor que absorbe la energía solar, transfiriéndola como calor, al fluido que circula en su interior y que puede ser usado en procesos que necesiten energía térmica.La eficiencia del sistema depende de la calidad óptica del espejo concentrador. En este trabajo, se determina la eficiencia óptica (&#951;op) de un disco parabólico prototipo, mediante un calorímetro que actúa como receptor, obteniéndose un valor &#951;op=0,71±0,02. Se valida el método aplicando el ensayo de barrido óptico de Hartmann modificado, resultando &#951;op=0,70±0,02 para el método del factor de intercepción y&#951;op=0,69±0,02 para la simulación óptica.]]></p></abstract>

This resource is limited and its availability finite. Solar energy can meet the needs of the global population. Concentrated solar energy uses a mirrored surfaces that reflects and concentrates the rays in a receiver that absorbs the solar energy transferring it as heat to the fluid that circulates inside it and that can be used in processes that need thermal energy.. The efficiency of the system depends on the optical quality of the concentrating mirror. In this paper, the optical efficiency(&#951;op) of a prototype parabolic disk is determined using a calorimeter, which acts as a receiver, being the value &#951;op=0,71±0,02. The method is validated by applying a modified Hartmann's optical scanning test, the values were&#951;op=0,70±0,02 for the of intercept factor method and &#951;op=0,69±0,02 for the optical simulation.]]></p></abstract>
