| 摘要 |
The invention relates to a laser-beam emission device (10) provided with an emission head including an optical unit (42) arranged in a generally longitudinal sheath (26), with a view to using same in contaminated environments. Said optical unit (42) includes a mirror (46) configured to deflect the initially longitudinal laser beam toward an outlet (20), thus enabling the laser beam to exit along an outlet axis (24) intersecting the longitudinal axis. The sheath (26) is configured to tightly confine the emission head such as to be impervious from dust. Thus, the emission head may be cleaned using decontamination products without the risk of damaging the optical unit (42) and the mirror thereof (46). |
