摘要 |
The invention relates to a hood for sucking-up fine particles, including: a mouth intended to be placed close to a wall, a base having a window through which a laser beam can pass, an intermediate portion between the mouth and the base, and a suction outlet disposed on the intermediate portion of the hood and designed to suck-up fine particles. The hood is characterized in that it comprises at least one air intake positioned near the base and, during operation, capable of creating a stream of air at the base of the hood so as to prevent fine particles from being deposited on the window. |
