Abstract

L'invention concerne un dispositif permettant d'usiner une pièce au moyen d'un faisceau laser. Ce dispositif comprend un boîtier optique (1), un logement (2) fixé au boîtier pour l'accouplement d'un guide d'ondes optiques émettant un rayonnement laser, un miroir de collimation (3) et un miroir de focalisation (4). Selon invention, le miroir de collimation (3) et le miroir de focalisation (4) comprennent chacun une surface de miroir présentant la forme d'une parabole hors axe. Le point central de la surface d'extrémité (7) du guide d'ondes optiques se trouve sur le foyer du miroir de collimation (3) ou près de ce foyer. Par conséquent, le miroir de focalisation (4) focalise le faisceau laser (5) sur le foyer du miroir focalisation (4) ou près de ce foyer. De préférence, le miroir de focalisation (4) est agencé de sorte que, les faisceaux individuels du trajet du faisceau laser arrivant sur le miroir de collimation (3) qui sont situés dans un plan de symétrie spéculaire du miroir de collimation (3) se trouvent dans un plan de symétrie spéculaire du miroir de focalisation (4) et que la série des points d'incidence (8a..8e) des faisceaux individuels arrivant sur le miroir de collimation (3), laquelle séries étant décomptée à partir de l'axe de symétrie de rotation (10) du miroir de collimation (3), coïncide avec la série des points d'incidence (8a..8e) des faisceaux individuels arrivant sur le miroir de focalisation (4) décomptée depuis l'axe de symétrie de rotation (11) du miroir de focalisation.
