Abstract

La invención se refiere a un dispositivo óptico para apuntar a lo largo de un eje óptico (Z) e indicar visualmente un área de lectura, que comprende al menos un conjunto de iluminación que actúa sobre una parte del área de lectura a lo largo de una vía de emisión óptica. El conjunto de iluminación comprende una fuente emisora de un haz de luz (3), un diafragma (4) que tiene una forma preestablecida, siendo dicho diafragma efectivo para seleccionar una parte del haz de luz generado por dicha fuente emisora de luz, y una lente convergente (5) situada en la vía de emisión óptica, corriente abajo del diafragma y adaptada para colimar el haz de luz conformado que procede del diafragma y se proyecta sobre una parte del área de lectura. El dispositivo de esta invención es al mismo tiempo económico y exacto (es decir, capaz de producir imágenes bien definidas), proporcionando con ello al usuario una indicación precisa del área de lectura a la que se apunta, independientemente de la distancia de esta al dispositivo.
