Abstract

On a mis au point un appareil d'amenée de faisceau comprenant un laser (10) ayant un axe (14), un premier miroir (13) à une extrémité du laser (10), conçu pour réfléchir le faisceau normal par rapport à l'axe (14) du laser, un second miroir (15) aligné avec le premier miroir (13), ledit second miroir (15) étant conçu pour réfléchir le faisceau le long d'un autre axe (16), un élément téléscopique (30) reliant le premier et le deuxième miroir (13, 15), un troisième miroir (19) aligné avec le deuxième miroir (15). Ledit appareil comprend également un moyen de focalisation (33) associé au troisième miroir (19) afin de focaliser le faisceau sur une pièce d'usinage. On a également mis au point un moyen de détection (63) destiné à détecter la distance d'une tête de focalisation (33) d'un système d'amenée de laser au-dessus d'une pièce d'usinage à soumettre à l'action du faisceau laser.
