Abstract

L'invenzione si riferisce ad un elemento sensore e di impostazione per regolare il fascio di laser ad alta potenza per la lavorazione di materiali, nel cui percorso del fascio esso è integrato e come unico elemento costruttivo consente contemporaneamente il rilevamento e la correzione di errori angolari ed errori di fuoco nei percorsi dei fasci di laser ad alta potenza. Viene illustrato un esempio di realizzazione.
