Au début des années 1980, on a étudié des photocathodes en arséniure d'indium-gallium mais la demande pour des tubes sensibles dans cette région du spectre est restée insignifiante jusqu'à l'apparition d'autres types de systèmes proche infrarouge tels que lasers état-solide et dispositifs à fibre optique.
