Abstract

Perfeccionamientos introducidos en aparatos tomavistas acoplados a (o mandados) por una célula fotoeléctrica, caracterizados porque el elemento fotosensible está dispuesto, por lo menos en parte, sobre una parte al menos de la superficie delantera del o de los elementos constitutivos (núcleos) del diafragma propiamente dicho, para ser batido por una parte de los solos rayos luminosos que pasan por el objetivo tomavistas.
