Abstract
Aparato para la discriminación de elementos extraños en ensayos ópticos, mediante medición de la concentración de partículas de tamaño medio en una mezcla dotada de partículas mayores y menores, siendo las partículas de tamaños medio y menor sustancialmente constantes en un campo macroscópico de observación y fluctuando las citadas partículas mayores en dicho campo de observación, caracterizándose dicho aparato en que comprende medios para dirigir un haz de radiación electromagnética a través de la referida mezcla de partículas; medios para establecer el referido campo de observación y para detectar y medir la dispersión en tal campo de observación del mencionado haz a lo largo e una dirección extra-axial respecto al haz.
